Every object in Catacomb has its own CcmbColor and name that distinguish it from other objects of the same type. Colors are also used in CcmbColor tables for displaying image data. The CcmbColor target editor is used for setting a single CcmbColor for an object, a line in a graph, or as part of a CcmbColor table.
The CcmbColor chooser uses the RGB system. In the lower window is a set of color axes: red is vertical, green to the lower left and blue to the lower right. There is a complete cube drawn in these axes, of which the forward vertex represents the current color. Any of the circles may be used to change the color. Those on the axes move only along that axis; those on the planes move in two dimensions, and the free axis moves in any direction. Random colors can be generated with the "new random" button, and the "keep" button records a sample of the color in the top window. These samples can then be selected with the left mouse button or deleted with the right button.
When changing a color, use the "apply" button to make the choice take effect.
