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. You can simply copy these two files to your own project.

Two frontends are included: a GUI for interactive use and a command line tool for scripting. The command line tool requires no libraries, the GUI requires Qt.

The following papers are implemented:
