The DLP 'rainbow effect' is an artifact unique to single-chip DLP projectors. The artifact appears as a rainbow or multi-color shimmer briefly noticeable when changing focus from one part of the projector screen to another. It appears as a secondary image that appears at the viewer's peripheral vision and is generally noticeable when shifting focus from a high contrast area or bright object.

3-chip DLP projectors, higher wheel speeds, 7-segment color wheels, and archimedes color wheel designs (pending) are minimizing or may altogether elminate the effect.
