Diffrent Colors for Point,Spot and Box lights?

[Slanderous]

Seriously, no offense, but is this thread a joke? Changing the light color is propably the easiest thing to do in Level Editor.

Back to the thread, click on your light (the lightbulb icon), in the "general" tab there should below "diffuse color" with white box next to it. Just click the white box and use the sliders to get the light that you want.
