While implementing the reader for GGF format I needed some test data and examples. A couple of articles on Wikipedia about bilinear interpolation and bicubic interpolation had examples in Matlab with some nice color maps.

A question of StackOverflow combined with another article helped me find a Mathcad implementation:

Also found a nice colormap - Haxby colormap:

Mathlab has replaced the default jet colormap with a new one called “parula”

Here is a graph of the RGB components:
