We don't want to toot our own horn here, but the principle is very simple:  if the original artwork is poorly drawn, then no amount of color is going to make it look good.

A lot of people are searching the net for color clipart, but the truth is, you're better off to start with a beautifully drawn black & white piece, and then you can experiment with subtle color schemes to create your own striking composition.

Here are some more samples of images from the RetroClipArt.com collection which are beautiful in b&w to begin with, so when you add color, they look that much better.
