Pure white light is actually made up of all colors. Without color there would be no light. When white light is split into its component parts, it produces a rainbow of colors. The same observation can be made when we see a rainbow in the sky. The prismatic effect created when light passes through the small droplets of moisture in the atmosphere actually bends the light into its spectral components. The reason we call this model additive color is because when all colors are combined they form white light.

When you look at a white sheet of paper in any light it appears white. That’s because our brains compensate for lighting irregularities automatically. No matter the lighting conditions, to your eye white always looks… white. Whether under candlelight or sunlight, fluorescent or tungsten, sunset or noonday, a white sheet of paper pretty much always appear white. This is because your brain retains “memory colors.” Unfortnately, your camera doesn’t! The camera records light quite objectively. The fact is… your brain is a lot more forgiving than your camera.Pure white light is actually made up of all colors. Without color there would be no light.

Chapter 1 “The Light and Color Show” in the Correct Color book goes into significant detail about these issues.
