I’m toying around with changing some visual elements of one web page (not a website), and I found some AMAZING tools:

Color Scheme Designer: This helps you see what colors go good with one another… very cool tool.

Flaming Text – Free Logo Designs: Put in the word, change some settings, and it gives you text with different visual characteristics.  Super cool.

Choosing Color Combinations: blog post that is excellent, from Veerle’s blog.
