"Coloured light on complementary surface" refers to the phenomenon where a surface appears to be a different color when illuminated by light of a different color. This is due to the way our eyes perceive colors and how different colors interact with each other on a surface.

“I find using LabSims really helpful as preparation before a practical. It's useful to be able to carry out some of the practical techniques online before completing them in the lab, and they make me feel more confident about attempting these techniques during our lab sessions.”

This phenomenon can affect our perception of color in several ways. It can make an object appear to be a different color than it actually is, depending on the light that is shone on it. It can also create interesting optical illusions and color combinations, which can be used in art and design.

The effect of "Coloured light on complementary surface" is caused by the way colors interact with each other. When certain colors of light are shone on a surface, they are absorbed while others are reflected. The reflected colors then mix with the original color of the surface, creating the appearance of a different color.

Yes, this effect can be seen with all colors. All colors have complementary colors, which are the colors that when mixed, produce white light. When a colored light is shone on a surface, the complementary color of that light will be reflected, creating the illusion of a different color on the surface.

Some common real-life examples of "Coloured light on complementary surface" include the color of objects under different types of lighting, such as how a white shirt may appear to be a different color under fluorescent lights compared to natural sunlight. Another example is the use of color filters in photography, where different colored lights are used to create different effects on a subject or background.
