12.1.12: Diffraction by a Row of Atoms - order of diffraction
SW Extra White was formulated to look great as a trim color with just about any Sherwin-Williams wall color, even dark colors on accent walls. My theory is that since the LRV is lower than many bright whites, it balances well with dark colors. It is also the base for many Sherwin-Williams paint colors.
The hallway was very shaded, so you can see that Extra White looks a bit dingy, but as an element of the total design, it adds relief.
Another interesting feature is that they used hardwood floors in the bathroom. It was a risk, but easier in dry Colorado than in other places. Wood floors also work better in Primary bathrooms than they would in children’s bathrooms.
Extra White is one of Sherwin-Williams’ most popular paint colors, and one of their top 5 best sellers, and one of the Top 50 Paint Colors. Many houses in North America use Extra White in one form or another, mainly as a white trim color. Extra White is also used as a base for many Sherwin-Williams colors.

We love the way this upstairs hallway looks painted with extra White. The light just bounces off the walls, and the green plants give it richness and life. Again, note the art on the walls, which keeps the area interesting.

The optical performance of an objective is dependent largely on the optical aberration correction, and these corrections are also central to image quality and measurement accuracy. Objective lenses are classified as achromat, plan achromat, plan semi apochromat, plan apochromat, and super apochromat depending on the degree of correction.
Extra White is a fairly neutral white paint color. While it does have cool undertones, they are not overly pronounced. Unless you use Extra White next to a very warm, creamy paint color, it looks pretty neutral. This is one of the reasons you can use Extra White trim with so many different wall colors.
As with many white paint colors, Extra White is like a mirror, so it will reflect other colors from your décor and green foliage from the outside. As a ceiling color, I have seen it reflect darker beige colors from the walls.
It can double the cost when you paint your trim with your walls. If you decide to paint your walls, trim, and ceiling, the price can be 2.5-3 times the cost of the walls alone. The time of the project can also be significantly extended.

However, in low light and in artificial light, Extra White looks blue next to Simply White. This is unusual, and most people won’t notice it or photograph it. I do because that’s my job, but it still looks great most of the time. That’s why I still have it in my house.
When you use Extra White as a wall color, you should pair it with colorful decor, warm wood finishes, and lots of art on the walls. Otherwise, it will look cold and like it was primed but not painted. Most people use Extra White as a trim color, in a Satin sheen.
Most microscopes rely on background illumination such as daylight or a lightbulb rather than a dedicated light source. In brightfield illumination (also known as Koehler illumination), two convex lenses, a collector lens and a condenser lens, are placed so as to saturate the specimen with external light admitted into the microscope from behind. This provides a bright, even, steady light throughout the system.

It’s not our favorite choice for exterior white paint because it can look cold. It works best when you pair it with a warm brown roof and even warm stone.
A basic compound microscope could consist of just two elements acting in relay, the objective and the eyepiece. The objective relays a real image to the eyepiece, while magnifying that image anywhere from 4-100x. The eyepiece magnifies the real image received typically by another 10x, and conveys a virtual image to the sensor.
Ultimately, I picked Extra White because it made more sense with today’s modern finishes and had more flexibility than Shell White. Shell White would have been perfect for the earthy color schemes in the mid-2000s.
Microscope objective lenses are typically the most complex part of a microscope. Most microscopes will have three or four objectives lenses, mounted on a turntable for ease of use. A scanning objective lens will provide 4x magnification, a low power magnification lens will provide magnification of 10x, and a high power objective offers 40x magnification. For high magnification, you will need to use oil immersion objectives. These can provide up to 50x, 60x, or 100x magnification and increase the resolving power of the microscope, but they cannot be used on live specimens.
There are some important specifications and terminology you’ll want to be aware of when designing a microscope or ordering microscope objectives. Here is a list of key terminology.
While most microscope objectives are designed to work with air between the objective and cover glass, objectives lenses designed for higher NA and greater magnification sometimes use an alternate immersion medium. For instance, a typical oil immersion object is meant to be used with an oil with refractive index of 1.51.
Even though I’m a color designer, I’m not immune to that effect. I’ve realized I’ll live with Extra White trim for as long as I live in this house. My house is my color lab, and Even though I paint my walls all the time as I experiment with paint colors, I’m too thrifty to repaint the trim. So, I have learned how to make Extra White look fabulous.
The home was painted before the white-and-black exterior trend, and the homeowner wanted to recreate a traditional East Coast look.
This popularity is what makes Extra White so important. As a color consultant, I learned quickly that I needed to learn how to work with Extra White.

This is one of those times when I had to compromise. Simply White looked beautiful in my living room, so it had to stay. I painted the fireplace wall with the dark SW Cyberspace (and later Hague Blue) because the Extra White mantle clashed with Simply White at night and really bugged me. Cyberspace separated the Extra White mantle from the Simply White wall color.

NEVER, EVER use paint matches from a different brand than the one specified. Results are poor, and there are no standards for the sheens. Even though your painter may genuinely believe it can be done, don’t do it. See results from paint matching here.
This home was one of our early projects with The Color Concierge, and it looks incredible. The homeowners had just moved into the house and wanted to make it their own. Previously, the wall color was a dated peachy beige. Of course, they had Extra White trim.
Coordinating other paint colors with SW Extra White depends on whether you’re using Extra White as a trim color, ceiling color, orwall color.
Still, Extra White looks like a very bright, crisp white thanks to its undertones. It could look softer and warmer, however, when paired with an even brighter white, such as SW High Reflective White.
Chantilly Lace has a higher LRV than Extra White. Extra White is more muted and has bluer undertones. It is much cleaner than Extra White, and I prefer Chantilly for trim and ceilings, especially with off-white paint colors.

There are two major specifications for a microscope: the magnification power and the resolution. The magnification tells us how much larger the image is made to appear. The resolution tells us how far away two points must be to be distinguishable. The smaller the resolution, the larger the resolving power of the microscope. The highest resolution you can get with a light microscope is 0.2 microns (0.2 microns), but this depends on the quality of both the objective and eyepiece.
A basic achromatic objective is a refractive objective that consists of just an achromatic lens and a meniscus lens, mounted within appropriate housing. The design is meant to limit the effects of chromatic and spherical aberration as they bring two wavelengths of light to focus in the same plane. Plan Apochromat objectives can be much more complex with up to fifteen elements. They can be quite expensive, as would be expected from their complexity.
Benjamin Moore Decorator’s White is much bluer and cooler than Extra White and not as flexible because of that. Decorator’s White is slightly darker than Extra.

I also painted my studio loft SW Cheviot, a Sherwin-Williams Designer Collection color. It looks almost identical to Simply White on the walls and has similar properties. In this case, Cheviot looked OK with SW Extra White as a ceiling color, although the ceiling looks darker and a bit dingy. Cheviot is a bit more muted than Simply White, but that is a story for another day!
While a magnifying glass consists of just one lens element and can magnify any element placed within its focal length, a compound lens, by definition, contains multiple lens elements. A relay lens system is used to convey the image of the object to the eye or, in some cases, to camera and video sensors.
When I built my home with a production builder in 2019, they gave me two choices for trim: Extra White or Shell White. Shell White was very, very creamy, and I felt that Extra White was too cool to be as flexible as I wanted.
Refractive objectives are so-called because the elements bend or refract light as it passes through the system. They are well suited to machine vision applications, as they can provide high resolution imaging of very small objects or ultra fine details. Each element within a refractive element is typically coated with an anti-reflective coating.
Extra White trim and ceilings look best with Extra White walls. I don’t recommend other white trim colors because the undertones can get tricky.
This hallway led from the primary bedroom to the bathroom. It’s a classic primary bath floor plan set up with large walk-in closets on either side. My current home has the same layout and I love it.
The reason that it’s so expensive is that it takes work to cut in the ceiling and trim lines. More labor means more cost. If you have the same color but different paint sheens, the painters still need to tape the edges and cut in the lines because they are different formulations and don’t look the same.
Both the objective lens and the eyepiece also contribute to the overall magnification of the system. If an objective lens magnifies the object by 10x and the eyepiece by 2x, the microscope will magnify the object by 20. If the microscope lens magnifies the object by 10x and the eyepiece by 10x, the microscope will magnify the object by 100x. This multiplicative relationship is the key to the power of microscopes, and the prime reason they perform so much better than simply magnifying glasses.
If your cabinets are Extra White, the cultural convention is to paint your trim Extra White. The window trim below is painted extra white to match the cabinets.

We always recommend that you test paint colors on your home because lighting can change a color completely, both with interiors as well as exteriors.
Historically microscopes were simple devices composed of two elements. Like a magnifying glass today, they produced a larger image of an object placed within the field of view. Today, microscopes are usually complex assemblies that include an array of lenses, filters, polarizers, and beamsplitters. Illumination is arranged to provide enough light for a clear image, and sensors are used to ‘see’ the object.
Although today’s microscopes are usually far more powerful than the microscopes used historically, they are used for much the same purpose: viewing objects that would otherwise be indiscernible to the human eye. Here we’ll start with a basic compound microscope and go on to explore the components and function of larger more complex microscopes. We’ll also take an in-depth look at one of the key parts of a microscope, the objective lens.
Pure White is warmer and slightly darker than Extra White. It has slight yellow undertones compared to the Extra White blue. However, you can pair Pure White as a wall color with Extra White ceilings and trim. In fact, I prefer to specify Pure White cabinets when a home has Extra White trim because they are warmer, softer, and more forgiving.
Benjamin Moore Ultra White is bluer, more muted, and slightly darker than Extra White. It’s more of a light blue-gray than white, and not as flexible as a trim color as Extra White.
Very creamy white paint colors, such as SW Shell White or SW Westhighland White, don’t work well with Extra White trim because the very warm undertones clash with the coolness of Extra White. But off-whites like Alabaster and Greek Villa can work. Be sure to always test before choosing any wall or trim color.
Although I wouldn’t usually recommend Extra White because it’s so cool, it worked well because of the warm accents on the roof and stone and the warm brown fence. In the summer, she had tons of flowers and trees.
Because it’s much easier and less expensive to transform your home if all you do is paint your walls. Painting trim and ceilings can be extended, messy, and intrusive. It is also just as expensive to paint your trim as it is to paint your walls because of the labor. The total cost of a project depends on the size and scope.
Numerical aperture NA denotes the light acceptance angle. Where θ is the maximum 1/2 acceptance ray angle of the objective and n is the index of refraction of the immersive medium, the NA can be denoted by
I don’t recommend Extra White for rooms with low light. The cool, blue undertones will make it shadow out in the corners of the room and can look dingy. Save SW Extra White wall paint for rooms with tons of natural light.

This house had tremendous light, making Extra White a perfect wall, ceiling, and trim color. There were many windows and skylights throughout the home. I have rarely seen a home so flooded with light.
In most cases, no. While Extra White is definitely a cool white paint color, it has enough pigment and depth that it won’t look stark on the wall. The only time it really risks looking stark is when used outdoors.
Extra White was beautiful in the Primary bathroom because it flowed well with the cool marble in the shower enclosure. It was a complete transformation from the previous peachy beige color.
Be very careful if you specify this color for your home interior because you need TONS and TONS of light. This wouldn’t work in a house like mine, where I have fewer windows, a covered back porch, and lots of shady corners. We rarely specify this white paint color as a whole-house color because it can look dingy in shadowed rooms at any time of the day.
I would not paint BM Extra White with much warmer Benjamin Moore white colors such as BM Swiss Coffee. Swiss Coffee is too warm and green to pair with Extra White.
Use Extra White as a trim and ceiling color if you have crisp white, clean white, or slightly off-white tile and other finishes. As a wall color, you need lots and lots of light, with walls of windows and skylights, to make Extra White work.

The SW Extra White ceiling looks dark because it has a lower LRV than Simply White. It’s a compromise that no one ever notices but me. My family doesn’t see it and doesn’t care. They are just happy with the brightness and warmth of the Simply White walls.
I use these in my color consulting practice for exact results. Discover Samplize peel-and-stick paint samples and click the button below to sample Extra White (Sample).
The only time I ever see homeowners paint their trim is when they move into a new house, renovate their home entirely from the inside out, or have a new build. If they paint 1-2 rooms, they leave the white trim color as is.
Absolutely! Lots of people use Extra White cabinets. But make sure you use it with crisp, clean quartz counters, Carrara and other cool marbles, and white backsplashes. Black countertops are always a classic and timeless look with white kitchen cabinets. Read more about this kitchen in this Coastal Cottage Kitchen Update.
In modern microscopes, neither the eyepiece nor the microscope objective is a simple lens. Instead, a combination of carefully chosen optical components work together to create a high quality magnified image. A basic compound microscope can magnify up to about 1000x. If you need higher magnification, you may wish to use an electron microscope, which can magnify up to a million times.
Below is a photo that shows Extra White trim and doors with White Snow. The door on the left has more light, and the one on the right looks cooler because it’s deeper into the hallway. They both look good, though.
We have written about a lot of different white paint colors over the years, but today’s color review of SW Extra White is one of the most important we’ve ever done.
I prefer SW Pure White as a trim color because it is more flexible. It pairs with a larger group of warmer whites and earthier finishes than Extra White does. That said, Extra White works – and we often don’t get a choice.
The working distance of a microscope is defined as the free distance between the objective lens and the object being studied. Low magnification objective lenses have a long working distance.
Oxford White looks a bit “off” with Extra White. In this photo, I show how Oxford White would look under Extra White (the trim under the counter acts as a “ceiling”). Oxford is lighter with a slightly higher LRV (89) than Extra White (86), and Oxford is cleaner and has less blue. Below, I painted Oxford White on the back drywall of my island to see how it looked with Extra White. I don’t recommend Oxford as a wall color with a darker ceiling color like Extra White.
(1) Pick wall whites darker than the ceiling white color. Walls that are lighter than the ceiling can make the ceiling look dingy. (2)Whiter walls can look ok with darker white trim. However, most people paint ceilings and trim the same white paint color.
The photos below were of a neighbor’s home near our old house (not one of our projects). They were taken in April before the trees grew their foliage to see the home better.
We tested so many colors, and Extra White was the best one. This was in 2018 before the black-and-white trend became popular, so it was quite a leap for the clients.
An microscope objective may be either reflective or refractive. It may also be either finite conjugate or infinite conjugate.
Hi! I am doing extra white on my upper cabinets, white oak on my Lowers and white quartz countertops with gold and taupe veins.. do you think alabaster would go for my walls? And then extra white for my trim?

My clients trust me to help them find the perfect paint color for their home – whether it’s a whole-house paint color scheme or ideas for a single room.
I was surprised to see how fantastic Alabaster looks with Extra white as trim and ceiling color. The Alabaster should have been too creamy but looks nicely balanced. This room is deeply shadowed with North-facing windows. Note that Alabaster is slightly darker than Extra White.
We kept the trim Extra White, then painted the walls and ceilings Extra White with a matte sheen. This was appropriate for the lofted ceilings because it was hard to find a place to cut in the ceiling color. Also, it saved lots of money on labor.
A reflective objective works by reflecting light rather than bending it. Primary and secondary mirror systems both magnify and relay the image of the object being studied. While reflective objectives are not as widely used as refractive objectives, they offer many benefits. They can work deeper in the UV or IR spectral regions, and they are not plagued with the same aberrations as refractive objectives. As a result, they tend to offer better resolving power.
Sherwin-Williams Extra White is one of the most common white paint colors found in houses in the United States – most commonly used as a trim and ceiling color.
One of the elements that make this room come to life is that there is art all the way up the walls. Otherwise, the room would look too bare, and bottom-heavy from the furniture.

High Reflective White is the cleanest color in the universe. It’s light and bright and has a very low pigment level. It pairs well as a wall color with Extra White trim, but I would not use Extra White as a ceiling color. HRW is so low on pigment that it can take many coats to get good coverage. Extra White can get good coverage on walls and trim with fewer coats.
The photo below is from the other side of the living room. You can see the green reflection from the foliage outside on the upper part of the walls. White paint can be like a mirror, and our homeowner said that he loved the way the walls and their color changed throughout the day as the light changed.
Here is the challenge in picking a trim paint color for your home: once you pick it, you will be stuck with it for the near or long term. Why?
That is why most homeowners stick with their original white trim color. It’s less expensive to touch up a chip in the trim than to paint the whole thing.
This family room had many warm finishes and rich brown wood timbers. We kept the brick fireplace, and the room just came to life. The room has windows and skylights everywhere to pull in warm beautiful light.
Extra White should be carefully considered as a wall color in rooms with North facing or cool light. The walls will look icy, but you should be fine if that is the look you are going for.

Most painters give their clients Extra White if they don’t know what trim paint white color to use. Many builders also use Extra White as their standard base trim color – and have for many years. I run into homes daily in my consulting practice with Extra White trim painted ten, twenty, and even thirty years ago.
Below is the SW Iron Ore accent wall with Extra White trim, ceiling, and stair spindles. The white wall on the right is SW Agreeable Gray. It looks great, although I recently updated the area and painted it SW Cheviot, which we show in a later photo.
Extra White has an LRV of 86, which is actually a bit dark for a white paint color. I would normally expect to see this LRV in an off-white paint color. So while Extra White is definitely cooler than a lot of other popular whites on the market, it’s really a softer white than you’d expect.
Avoid Extra White if you have creamy or yellowish whites in your décor or hard surfaces. The chandelier in this dining room was too creamy and earthy, and the homeowners changed it after the home was painted. The yellow lemons in the pitcher look great, though!
Extra White is a versatile trim color, but if you want white walls with Extra White trim, it’s important to choose (and test) carefully.

Greige colors such as Agreeable Gray also look good with Extra White trim. Below is a photo of Agreeable Gray in the stairway shadows and with the sunshine streaming through. It looks very nice with Extra White. You can see part of an Extra White ceiling in the top right corner. The stairway spindles and trim are also Extra White.
We usually use a brighter white for the ceiling than the trim and the walls. Although some people think they are the same color, they are not. It will be fine if you already have Ceiling Bright White on the ceilings and want to paint the walls and trim Extra White. No one will notice.
SW White Snow (LRV=90) walls look good with Extra White (LRV=86) trim. White Snow is lighter than Extra White. Although the Extra White trim is darker, they look good together. For this combination, the ceiling should be White Snow. An Extra White ceiling would look dingy because it’s darker than White Snow.
The eyepiece or ocular lens is the part of the microscope closest to your eye when you bend over to look at a specimen. An eyepiece usually consists of two lenses: a field lens and an eye lens. If a larger field of view is required, a more complex eyepiece that increases the field of view can be used instead.
Well, that depends. If you paint your house with Extra White, you need to use primer and/or stick with the higher grades of exterior paint, such as Duration or Emerald. It’s a low-pigment color, and you may need to paint more than two coats.
It can look stark outside as a white exterior trim color, especially next to darker siding paint colors. If you use SW Extra White as a trim color, pair it with lighter paint colors. It’s usually not our first choice for white trim. In fact, we have never used Extra White as an exterior white trim color. When we test, it always looks too stark.
The parfocal length of a microscope is defined as the distance between the object being studied and the objective mounting plane.
I also wanted to show how SW Extra White looks with my beloved Benjamin Moore Simply White walls. During the day, when the room is flooded with light, Extra White trim looks fine paired with Simply White, although the ceilings look a bit dingy and dark.
A microscope is an optical device designed to magnify the image of an object, enabling details indiscernible to the human eye to be differentiated. A microscope may project the image onto the human eye or onto a camera or video device.
Driven to help clients fall back in love with their homes with intentional paint color schemes. She started the company based on her passion for color and its ability to make a house a home.
It can be, especially if most of the house has lots of natural light! While we often recommend a warmer white for whole-house color schemes, Extra White can look really beautiful with the right decor, furniture, and hard finishes. In the client project spotlight below we used Extra White throughout many spaces of the home.
The field of view (FOV) of a microscope is simply the area of the object that can be imaged at any given time. For an infinity-corrected objective, this will be determined by the objective magnification and focal length of the tube lens. Where a camera is used the FOV also depends on sensor size.
We agreed that a white foundation color suited the architecture of the house. It had lofty ceilings and lots of architectural interest. It may seem counterintuitive, but white and light colors make architectural features stand out. The shadows and light do the work of highlighting it for you.

Ceiling Bright White is darker than Extra White but has the same blue undertones. If you paint your trim and/or walls Extra White, I recommend Extra White instead of Ceiling Bright White, which can make extra white look dingy.
If you’re going to use SW Extra White exterior paint, make sure to pair it with warm stone and a warm, brown room to keep it from looking too cold.
Although we always prefer to recommend the “perfect” white trim color for a home, we must understand how Extra White works in order to coordinate other paint colors with Extra White trim and ceilings.
