You can easily buy 60 watt lightbulbs which are red, yellow,
blue or green for party lights.

Not really, you get different proportions of the wavelengths but
the eye adjusts and you probably wouldn't notice a difference in
color.	Exception:  a brown dwarf shines at only about 1000-1200
degrees, so it would have red light.  The main things that would
affect it, I'd think, would be the density and composition of
the atmosphere; however, I'd expect the local variation in
vegetation to be more important.
