Quake 2 colored lighting is set through decimal RGB color values, similar to html text colorations using hexadecimal RGB values. For those of you who want to get really anal and/or extravagant about your light colors: here is a fairly substantial list of options, not complete mind you... :)

Here's two screenshots, from the same exact spot, in the same map, one in glQuake2 at 512x384 and one in normal Quake2 at 512x384. You guess which is which.
