composite color raster object:  A raster object in which each cell contains a data value representing one of the colors into which all available color data for that cell has been compressed.  For 8-bit raster objects, there are 256 possible colors for each cell; for 16-bit raster objects there are 32,768.  Composite color rasters are usually compressed from a red/green/blue raster set that retains a wider range of color information.  The composite raster still produces near photographic quality color displays.
