Pixel Diva has the scoop on coloring tools. I love to play with color, so I'm putting these links here for safe-keeping:
- Color Match. Nice simple tool that suggests a 6-color scheme for your blog when you slide a slider. Has the hex numbers too.
- Color Toy. Another simple fun tool with a random button that I couldn't stop pushing.
- Color Scheme. You have to see this to believe it. You choose different color scheme methods: monochromatic, base + complement, split-compements, etc. Has extra settings to let you see what your colors look like with various kinds of color blindness. Great tool to learn about color and pick colors!
