well, this would all depend on the color of your hair, eyes, etc...
i'll guess you've got red hair, since your avatar kind of hints at it... maybe a dark red? so for your eyes, i'd say a brighter shade of olive green on your upper lids, then a darker shade of either olive green or brown on your brow bone (not your eyebrow, you know the bone that kind of sticks out from your eyelid? that bone... :D)... and those colors will work best with brown eyes and blue eyes... green eyes, not so much...
for green eyes, i'd try just a neutral brown for the lids and a darker brown on the brow bone.
usually you can put about three coats of mascara on before it'll start to look like you're trying too hard. three coats is good. optional thin black liner on the top, thicker on the bottom. light peachy blush is really hot.
these will really only look super "hot" during the evening time... for daytime, less is more. just use lighter shades, less dramatic (maybe just one shade) and guys aren't huge fans of foundations and powdery faces... guys really like the natural look a lot more than women believe. :)
but beyond makeup, use your personality. :D that's what will never fade or wash off...
