Custom Colormaps¶

The following demonstrate the construction and application of custom color mapping using the Color Map Utilities along with surface shading and highlighting. In most of the following examples, colormap objects are created to be used to construct the final colormap.

Single Variable Colormaps¶

A two-color colormap is used to contrast the inner and outer surface.
