Some devices can display simultaneously a fixed number of colors (typically 156), chosen from a much larger number of colors (often more than 256000). An application can use the palette manager functions to take advantage of the extra capabilities of these devices. These functions enable an application to change the colors in a device's physical color table and the displayed colors rapidly without explicitly redrawing the screen.

An application can use the CAPS_ADDITIONAL_GRAPHICS option of DevQueryCaps to determine whether the display device supports palette functions.
