Color Consultant Pro for Mac

From Code Line Communications:

Color Consultant Pro (CCP) is an interactive color wheel. It is designed to help artists of all kinds apply color theory to design effective color schemes. Like a traditional color wheel, CCP gives visual guidelines to how colors work together. But Color Consultant Pro goes beyond what a traditional color wheel can do.

Color Consultant Pro supports both Scientific (additive/RGB) and Artistic (subtractive/RYB) color systems--something nearly all color wheels on computers have failed to support. In addition, color schemes can be saved and exported to various formats* for use in other applications.

It supports both the Artistic and Scientific color systems using Analogous, Complementary, Split Complementary, Monochromatic, Tetradic and Triadic schemes. Color information can be entered and retrieved using RGB, CMYK, HSB, Lab and Websafe RGB. Colors can also be sampled on-screen and applied to the color wheel.
