Color Tools
Search for colors, color schemes, and color inspiration.  Many of my links I've found from other sites.  I'm trying to setup a place where I can find them easily whenever surfing the Web.  Thanks Cameron Olthius at http://www.cameronolthuis.com/2006/01/75-helpful-web-design-resources/.

Colourlovers - I’ve found some great color inspiration and color schemes from Colourlovers. Currently more than 39,000 colors and 16,000 palettes.
Colour Contrast Check - From Jonathan Snook, the Colour Contrast Check Tool allows to specify a foreground and a background colour and determine if they provide enough of a contrast “when viewed by someone having color deficits or when viewed on a black and white screen”. The tool will indicate that the colours pass the test if both the colour difference and the brightness difference exceed their threshold. It will indicate that it sort of passes if only one of the two values exceed their threshold. And finally, it’ll fail to pass if neither value exceeds its threshold.

The Color Wizard - This is my favorite color tool on the web. I wrote about The Color Wizard a couple weeks ago. The Colour Wizard lets you type in the value of your colour and get an automatic return of that colour’s complementary colour, split complementary colours, analogous colours, chromatic variations, shade and tint variantion and saturation variation.
ColorCombos.com - Color Combos allows you to test color combinations, see how the different combinations work together on screen, and gives color combination ideas. You can also pull colors from other websites by simply entering in the URI.
