Divide by 255 (since this is the maximum possible value). Also set diffuse
to 0 if you have light sources. If there's still a difference (if POV-Ray's
output is lighter than the specified color), it may be due to gamma
correction.

Probably. All you need is for the object you want to glow to have a high
ambient value (you already have this), and for other objects to be around
it. Then add radiosity{} to your global_settings{} block, and the other
objects will be lit up by the one with high ambient. The hard part is
tweaking the radiosity settings to make it look good. =)
