Note that not all pairs of <$x$> and <$y$> coordinates correspond to physically realizable color values; others correspond to imaginary colors, which cannot be generated in practice.

For example, there is the widely used CIE chromaticity diagram (see Figure 1) with normalized coordinates <$x$> and <$y$>, calculated from the XYZ values of CIE XYZ color space. One may consider the shown two-dimensional color distribution as one plane (for one particular brightness) of the three-dimensional color space.

Concave mirrors are used in light collection applications or as focusing mirrors in imaging systems. Newport's concave metallic-coated mirrors on Borofloat 33 substrates provide a good combination of performance and value. They operate over a very broad spectral range – including UV to visible and visible to near-IR – with no chromatic aberration. For ultrafast applications, see our Ultrafast Optics Guide for more information on our concave mirrors designed specifically for use with ultrashort pulses.

Note that the sometimes used term monochromaticity is not related to the concept of chromaticity as explained above; it is essentially a non-quantitative term for how close certain light is to be monochromatic.

Note that not all color spaces use luminance as one of the coordinates. For example, RGB color spaces have red, green and blue primary colors, and the values of all coordinates need to be changed if only the luminance is to be modified. One can then not identify any of the coordinates as pure chromaticity coordinates.

Up-to-date technical know-how is the key to success in photonics. RP Photonics offers high quality training courses at your location:

If the chromaticity is held constant, variation of the luminance coordinate only makes the color brighter or dimmer, but without changing its characteristics. For example, one may choose some kind of white, as seen for high luminance, and get that transformed into gray towards black and reducing the luminance; at all points one has a “neutral” color impression. Similarly, one may go from a dark red to a bright red without changing chromaticity.

In many technical applications, perceivable colors are represented by coordinates in some colors space. Usually, such a space has three dimensions, corresponding to the three different kinds of color receptors used for photopic vision of the human eye. Frequently, one takes one of those dimensions to correspond to the luminance, determining the perceived brightness. The remaining two dimensions are then interpreted as the chromaticity, defined through two coordinate values. The meaning of those coordinates can be very different, depending on the used color space. For example, chromaticity may further be divided into hue (“type of color”) and color saturation.
