Color palettes for Stata graphics: An update

This article is an update to Jann (2018a, Stata Journal 18: 765–785). It contains a comprehensive discussion of the colorpalette command, including various changes and additions that have been made to the software since its first publication. Command colorpalette provides colors for use in Stata graphics. In addition to Stata’s default colors, colorpalette supports a variety of named colors, a selection of palettes that have been proposed by users, numerous collections of palettes and colormaps from sources such as ColorBrewer, Carto, D3.js, or Matplotlib, as well as color generators in different color spaces. Furthermore, a new command called colorcheck is presented that can be used to evaluate whether colors are distinguishable by people suffering from color vision deficiency.
