ColorBrewer palette names are predefined in ChimeraX and summarized in the tables below. Only a selected number-version is shown for each name, with the range of available numbers given in parentheses. Capitalization of the name is not important. All versions can be previewed (albeit without their names) and assessed by other criteria such as suitability for colorblind viewers at the ColorBrewer website.
