So Many Schemes

Here are some of my favorite online tools for exploring and manipulating color. What tools do you use?

Color Blender — Very convenient tool to blend any two colors with a varying number of midpoints

A list of colors by name and color code — for those of us who are color blind, this is very helpful for looking up colors by name.

Color Code Chooser — tool helps you manipulate colors in a number of very helpful ways.
