These tools generate color maps for visualization. A variety of methods for sequential, diverging, and qualitative maps is available.

The color map generation is contained in just two C++ files (colormap.hpp and colormap.cpp) and requires no additional libraries.

Two frontends are included: a GUI for interactive use and a command line tool for scripting.

The following papers are implemented:
