I see colors everywhere...
CHColorMapControl is a Cocoa control that allows the creation, editing, saving, and opening of NSColorLists. An example of this control is used in the settings for our Fluid screensaver to edit colormaps. It handles smooth gradations between colors or it can be set to show solid color swatches between positions. It handles color opacity values and shows transparent colors with a grid behind them (very much like Photoshop does with layers).

There is a sample application included in the CHAppKit package that is a standalone colormap editor which can be used to save OS X-standard colormaps that, when saved to your "Colors" library directory, can be used in the standard color picker within the OS. As far as I know, this is the only such control or application that deals with Apple's colorlist data.

Programs using CHColorMapControl (that we know about):

• Fluid Screensaver

Note: CHColorMapControl is in constant development as I see new uses or needs for it. Because of this, feel free to offer hints, advice, kudos, or complaints so that I can make it better.
