Aside from the monochromatic and colorbrewer color bars, almost all IDL colorbars suffer from extreme deficiencies in perceptual uniformity and colorblind friendliness. png files located in the IDL_py_png directory, which apply the python-based sequential colormap analysis tools to the IDL builtin maps. These colorbars are better than most of the builtin IDL default colorbars. Included is a new IDL colortable file with the new Matplotlib perceptual colorbars, as designed by Stéfan van der Walt and Nathaniel Smith ( ). These slides are also included as a PDF file in this repository. To learn more about why to use perceptually uniform color maps, as opposed to the more typical rainbow color map ubiquitous in science, look at these slides I made, as well as the embedded references. This repository is designed to get decent colormaps into IDL.
