From the developer:
ColorDial is a rich and powerful, open source color wheel/picker for OS X. ColorDial sports a magnified reticule for picking the exact color you want with the eyedropper tool, colored sliders to help you fine tune your perfect tint and hue, a color wheel to find your complementary color shemes and the ability to copy CSS ready definitions when you're done.
