Light & Color

Colored Shadows

COLORED SHADOWS reveals the colors hidden in white light. Red, green and blue spotlights shine on a wall. The wall looks white because red, blue and green light combine to make white light. As visitors walk in front of the lights, their bodies cast three different shadows. Wherever a shadow blocks one color of light, the other two colors combine to produce a new complementary color. A person standing close enough to the wall can create six different colors, plus black and white.
