Pixie is an easy to use, fast, and tiny utility designed especially to fit the needs of Webmasters and designers. It's a color picker that includes a mouse tracker. Run it and simply point to a color, and it will tell you the hex, RGB, HTML, CMYK, and HSV values of that color. You can then use these values to reproduce the selected color in your favorite programs. Pixie also will show the current
xy position of your mouse pointer. It's the only tool you'll need for working with colors.
Version 3.1 adds a free mode and the ability to redefine hot keys.
