Do - it - Yourself kit to learn that the light that we all perceive as white is actually a mixture of many colors.  Do - it - Yourself kit to learn that the light that we all perceive as white is actually a mixture of many colors. How It Works Our eyes work a lot like video cameras and can perceive roughly 30 pictures per second. The time it takes to capture one picture is called the integration time. When the color disc is still, you can see each individual color clearly. When you spin the disc quickly, though, each of the seven colors whiz past your eyes during the integration time. When this happens, your eye starts adding the colors together. The disc then appears to be colored solid grey or white.
