Colors
There are two groups of colors:
- a standard set of fixed, named colors that are always defined.
Named colors use index numbers
starting at 0 and decreasing to -19, since there are 20 named colors.
- a dynamically loaded colormap that can be changed at will.
Dynamically loaded colors use color indexes starting at 1 and increasing to the number of colors
in the colormap. See COLORMAP
and
COLORMAPFILE
.
The named colors are shown below.
