I don't like it when a girl uses a hell of a lot of makeup. Girls with too much makeup just aren't attractive. However, no makeup can be alright, though I do like girls wearing a bit of makeup. As a guy I quite like to see girls wearing a bit of makeup, but if the girl in question is someone who I find quite attractive (and I don't just mean physically, but in all respects), then I'll probably see that girl as being attractive even without makeup, and possibly even with bed hair and half asleep first thing in the morning. As it were.
That said, girls who wear fake tan, I don't like. A natural tan is fine, but fake tan is horrible, especially if they're wearing so much that they look orange (David Dickinson style). That's just an instant turn-off. Paler skin is okay though (for example, my brother often ridicules me because I find Nicola in Girls Aloud, the pale redhead, more attractive than the others).
