Newton's color disk: When rotated,appears white.

Newton's Color Disk: When rotated, appears white. Newton's Color Disk is mounted on a motor shaft. When the motor is turned on, the disk rotates rapidly. The segments of color on the disc are apportioned so that, when the disc is rotating, an approximate white is formed by the mixing of the colors. This whiteness is never quite realized due to the impurities of the colors, but the effect is muddy white. The effect is intended to convey the idea that the persistent effect of the different colors on the retina of the eye is the mixture of all the colors, namely - white. Note: Leybold Rotator pulleys are set for the highest speed.
