4 years ago I made this map. It was called "daltonic" and had randomly placed colored lights.

4 years later I decided to pick up that map again and rebuild lighting. As the name suggests, the idea of this map came literally from http://en.wikipedia.org/wiki/File:AdditiveColor.svg

Looking at it now gives me some ideas to make light colors dynamically affect players, but that's either impossible with id tech 3 or I'd have to program it myself...
