Color System

The color reference hub for dartwork-mpl. Browse complete palette sheets, explore colormap collections, and dive into the Color class for programmatic manipulation in perceptually uniform color spaces.

Looking for a quick how-to? See the Colors and Colormaps guide for practical usage patterns, named color shortcuts, and mixing utilities.


Named palette catalog

All named palettes rendered as full-width sheets — use library.colorweight anywhere matplotlib accepts a color string (e.g. tw.blue500, oc.gray6).
