Wavelike Behaviors of Light. The previous lesson focused on the principles of color addition. These principles govern the perceived color resulting from the mixing of different colors of light. Principles of color addition have important applications to color television, color computer monitors and on-stage lighting at the theaters. Each of these applications involve the mixing or addition of colors of light to produce a desired appearance. Our understanding of color perception would not be complete without an understanding of the principles of color subtraction.

Color perception, like sound perception , is a complex subject involving the disciplines of psychology, physiology, biology, chemistry and physics. When you look at an object and perceive a distinct color, you are not necessarily seeing a single frequency of light. Consider for instance that you are looking at a shirt and it appears purple to your eye. In such an instance, there may be several frequencies of light striking your eye with varying degrees of intensity. Yet your eye-brain system interprets the frequencies that strike your eye and the shirt is decoded by your brain as being purple. The subject of color perception can be simplified if we think in terms of primary colors of light.

Drag any colored circle to change overlap region. In the addition choice you could imagine the primary colors red, green and blue to be projected on to a white screen. The rest of the screen is unilluminated and hence black; The region where they overlap gets a different color which depends on which two colors overlap and their brightness levels. In subtraction, you could imagine the colors Cyan, Yellow and Magenta to be painted on a white paper. White light goes through these transparent colors each of which acts as a filter removing a certain color as light passes through it and after striking the paper passes through it again.
