Each color map shows some example usage and provides color tables in CSV format so that they can. The color maps are organized by how and where they are best used. More specifically, this page provides color maps that you can use while using pseudocoloring of a scalar field. There are also external libraries like palettable that have many extra colormaps. This page provides advice for using colors in scientific visualization. Its status as the default was quite unfortunate, because qualitative maps are often a poor choice for representing quantitative data.Īmong the problems is the fact that qualitative maps usually do not display any uniform progression in brightness as the scale increases. Matplotlib has a number of built-in colormaps accessible via lormaps. The jet colormap, which was the default in Matplotlib prior to version 2.0, is an example of a qualitative colormap.
