In case this would help anyone, I've written up a tutorial for some of my more icon-illiterate friends. I thought I'd post it here since it's technically a tutorial, though most of you are probably already familiar with the technique. Anyway.

This is a tutorial for PSP7 (fully translatable), with a little bit of knowledge of the program necessary beforehand. It's for color and lighting effects.
