slightly shifted. Then, the third color gets displayed (blue, for example), and the eye sees that frame's color slightly shifted again. This effect is not perceived only for the moving object, but the whole picture. Multi-color LED-based and laser-based single-chip projectors are able to eliminate the spinning wheel and minimize the rainbow effect since the pulse rates of LEDs and lasers are not limited by physical motion. Three-chip DLP projectors function without color wheels, and therefore do not manifest this rainbow artifact."
