Goal: Learn about colors and colormaps in CDAT/VCS.

The colormap in VCS consist of 8 bit color map : 256 colors. Each color has unique name associated with itself.

VCS is currently limited to ONE colormap at a time, but if you clear your plot, you can use multiple colormaps during the same session.

The colormap GUI in VCDAT let's you easily pick/change colors and the colormap

 

There can only be one active colormap at any given instance, and there is always an active  colormap.

A colormap contains 240 user definable colors and 16 immutable colors.

The color mixtures are defined in terms of percentages of red, green, and blue colors (0 to 100% for each).


The immutable colors are, in order:

240-white,
241-black,
242- red,
243-green,
