ID Code: N3-08
Purpose: Demonstrate color mixing.
Description: Spinning the color wheel on a fast rotator while illuminating it with a bright stroboscope produces a variety of color mixtures. For example, fourfold symmetry would imply that the color is produced by a mixture of four primaries: G+G+B+B = saturated cyan. Others include 2R+G+G+B = R+G+( R+G+B ) = Y+W = unsaturated yellow, and B+B+2R+G =B+R+W = unsaturated magenta. The photograph at the right shows the color wheel rotating while being illuminated by the stroboscope blinking at the rotation rate of the wheel.
