A subset of the color look-up table that establishes the colors that can
be displayed on the monitor at a particular time. The only color depth
that allows multiple palettes is the 256 (or 8-bit) color setting for your
monitor. At a color depth of 256 colors, each program (or even each
individual image used or edited in a program) can have a different
color palette.
The flashing that occurs when your monitor is set to a color depth of
256 colors and you switch programs. When you switch programs, the
palette of the active program becomes the system palette, and all other
programs redraw themselves as accurately as possible with the new
colors.

GIF cannot.
