Wondering how (or even if) you can create your own color palettes? Well, I've just posted a tutorial on Colormusing's main blog, A Musing, designed to get you started by picking colors from a photograph. (This is a great way to make use of photos that may not be that wonderful in quality, but which have pretty colors. Even if it's digital, why waste it?)
With lots of screen shots and a step-by-step explanation of the process, you'll be making palettes before you know it!
