Color Schemes lets you put together up to 28 color schemes, each with up to three colors. There are two modes. In "Manual" mode you select all three colors; in "Automatic" mode, you select one color and two colors are generated for you using 120 degree color wheel separation. Red, Green, and Blue components of each color are selected using sliders, typing in decimal or hex values or using the Color Picker. You can drag and drop (Control key held down) color from any window to any other window. Color data is saved between sessions.
