Document Summary

Partitive mixing in close proximity spatially: small colored light sources, such as red, green, and blue dots (pixels or painted dots), are placed side by side.

A dlp projector uses a rotating color wheel of primary colors and a few other colors (to broaden the color pallet) and a very bright full spectrum white light source.
