The Palette Manager monitors the color needs of the graphics environment. The Palette Manager can track the combined color and grayscale requirements of your application, other applications, and the Operating System, and it can do so across multiple screens. The primary purpose of the Palette Manager is to ensure that the best set of colors is available for display devices with limited color capabilities. For example, on a device that can display 16 colors only, an image composed entirely of earth tones will lack all subtlety and richness because the default color lookup table for the device provides a broad set of colors spread across the color spectrum. With the Palette Manager you can create a palette containing a range of 14 earth tones (you must provide black and white as well) and attach it to a window to get the best display possible for your image. This palette can be attached to one particular window and needn't affect the color display of the Finder, of other applications, or of other windows in your application.
