standard 64 annotation colors:� In 8-bit contexts the Color Palette Editor window normally reserves the first 64 colors for a standard set of user annotation colors for text and overlays.� That leaves 192 colors for the image itself - ample color space for representing most natural color images to the human eye.� The 64 standard colors are chosen at fixed intervals in the RGB color model.� They generally appear brighter and purer than the subdued natural tones of the underlying image.
