Each chosen color space will open as a separate Java frame. The frames are synchronized, to show each color's representation in all color spaces simultaneously. All frames contain controls to specify color coordinates and have colored rectangles at the bottom indicating the current color. When you leave this page, all active frames are disposed of automatically. To see this in action you need Java-enabled browser.
All frames are very easy to understand and work with.
The RGB frame contains the wire-frame RGB cube with colored vertices. The grey ball represents the current position. You can 3D-rotate the cube by dragging the mouse. Saturation always ranges from 0 to 1, and specifies relative position from the vertical axis to the side of the hexcone. The colored hexagon on the left is a horizontal slice of the hexcone, shown on the right as a light-grey plane.
