Color palette is an array of colors. Each pixel of image reffers to color by index in color palette. Images in GIF- files can contain up to 256 colors. Therefore color palettes of multicoloured images will be transformed to 256 colors. See: add image to GIF; paste image from clipboard, Image Collections, Button Creator; frame operation merge; animation scripts.
There are two kinds of palettes: global and local.
Local palette defines colors for individual image inside GIF- file. It demands some extra memory in GIF- file to be stored. Local palette may be absent, and global palette is used for that case.
