Trouble Choosing Colors?

A while back Adobe introduced Kuler to help with choosing and sharing color palettes that work well together. While I still haven't really made much use of this tool, I'm convinced that I should.

Today I ran across a blog entry from a site that takes a similar approach to sharing color palettes, COLOURlovers.com. In this blog entry they show the color palettes of a few very famous paintings. These are obviously some nice color combinations that I should try sometime.

• Have you tried using Kuler or COLOURlovers?
• Have any favorite color palettes to share?
