Don't compare yourself with the pics in the magazines. They're fake. Take a look at this thread to see just how much work and editing goes into those pics.

If you need to compare yourself with someone, look at real women around you instead. Anyways, my tips are to look for "natural" colours that are close to your own for lipstick, foundation, rouge, and avoid weird colours around the eyes like blue or green. Stick with browns and greys. Put on your make-up in light as similar as possible to the light in which you are going to be seen. Rouge is strange, it somehow takes a short while to "set", so after about a minute the colour will be much more intense than when you had just put it on. At least in my experience. So be very careful with the rouge.
Just today I nearly asked a woman in her late 30's for ID when she bought cigarettes because her make-up looked like a 14-year-old who had just begun to experiment with make-up. RED cheeks (I mean really red, two distinct blotches!), mascara so thick the lashes had lumped together in little spikes, shimmery blue eye-lids, and some weird mother-of-pearl colour on the lips... Eurgh.
