direct graphics

Load a color table by index. This routine is directly analogous to LOADCT, but with more color table options.

The default color tables:

The Brewer color tables are split into three types: sequential, diverging, and qualitative. Sequential color tables are simple sequences from white to a given color. The diverging color tables have white in the middle of the color table and progress in each direction towards two different colors. The qualitative color tables contain only a few colors for labeling purposes. The qualitative color tables are expanded to take up the same space of the other color tables in the graphic below:

The GMT color tables:

The Yorick/Gist color tables:

The matplotlib color tables:
