Chuck Greens design blog, PagePlane, offers a wealth of information. Yesterday I found a link to The Color Scheme Designer that was created by Petr Stanicek. He's from the Czech Republic, EU, and is a professional web designer and online application programmer. How cool is it that he's made this fun tool available for free!
Click around on the Color Scheme Designer. The little circles at the top, left, let you choose different kinds of color schemes. You can move the dots on the color wheel to change the schemes you get. Honestly, you could lose all day playing with this.
