There is a semi-official 'web safe' palette, but these days pretty much all
palettes are web safe so I wouldn't bother. Besides, the few computers that
still reduce the colours won't look all *that* bad.

If you're talking about exact colour rendering (Pantones etc), there's no
way to get them right, but the PNG format helps a bit because you can store
gamma information (although I'm not sure which browsers will use it, and
anyway most users won't have their browsers set up for it).

I tend to just get the images looking right on a monitor set up for sRGB,
and hope they don't vary too much in the wild.
