O3-01: COLOR PERCEPTION IN SHADOWS - SLIDE PROJECT

ID Code: O3-01
Purpose: Demonstrate complementary color shadows.
Description: A white (clear) slide and a colored slide are superimposed on a screen with the intensity of the colored slide decreased such that the entire field looks white (or maybe slightly off-white). When an object is held in the light path two shadows are created: the shadow of the white light is the color of the second slide, but the color of the shadow of the colored slide is not white, but rather the complementary color to the colored slide. For example, a red slide makes a cyan shadow, a green slide makes a magenta shadow, and a blue slide makes a yellow shadow.
