Funny, I wrote a Hub about this a few weeks ago. Basically, it depends on the occasion. If you are going out to a dark club, it doesn't hut to lay it on thick, with lots of color. It is expected there, and the darkness hides how heavy it is.
Also, think about why you are making up. Who are you trying to impress? Most guys don't like to see loads of makeup. We wonder what you are trying to hide. Makeup works best if it is invisible, add a hint of color, make your eyes look bigger and brighter. Guys joke about heavy makeup on girls.
But really it varies a lot depending on your age and who you hang out with. Look at your friends and try not to be the most made up one there, and you won't look trampy unless all your friends are really trampy.
