This exhibit gives children a rare opportunity to mix colored lights instead of pigments. Three light sources of primary colors - green, red and blue, shine down on a white table top. By placing the hands just above the table top, the user cast a shadow of different colors depending on which colored light is blocked. The combination of red, green and blue light produces white light. If the hand blocks one of the colors, the resulting shadow cast is the complement of that color. For example, if the red light is blocked, the shadow cast will be cyan colored. This exhibit demonstrates the principles behind how color televisions and monitors work.

Colored Shadow is available in the "I AM a Scientist" travelling exhibit package.
