I was of the opinion (and I don't know where I got this from) that stars are not comprised of many compounds - eg. the sun is made of primarily helium if I remember correctly. So the colors would be limited to the photons that could possibly be released from drops in the limited number of energy states of the primary element, or it's ionic form which I believe is also commonly the case.

If I have my facts straight, I don't know how energy levels could have nothing to do with a star's color (or only give "miniscule corrections"). I'm fairly certain that the only way to produce a photon is by changing the energy level of a subatomic particle, so the energy levels of the electrons in the atoms (and the frequency at which they are occupied and vacated) would have to directly determine the color.

. . . Someone who knows more about this than me, please set me straight.
