Fortunately, there are several good sites that can help you choose a color scheme for your site. Here's a by-no-means-exhaustive list of a few of my favorites:
- Web 2.0 Colour Palette - helpful for picking out the latest and freshest colors to give your site a Web 2.0 feel.
- Color Palette Generator - upload your favorite photograph and Color Palette Generator will create a color scheme from it.
- Color Schemer Online - one of the oldest and still one of the best. Pick a color you like and color schemer will generate a palette of colors that blend nicely with the color you chose. You can also browse through color schemes created by other people at Color Schemer Gallery.
- Daily Color Scheme - lots of cool color palettes to choose from here.
- HGTV's Color Tool - This site focuses on choosing colors for your home, but it's a useful place to pick up inspiration for color schemes you don't see all over the web.
That's my list - if you know of any that should be mentioned, please leave me a comment.
