Colormate is an add-on that simplifies color management within the Blender shader graph. It allows users to calculate color harmonies directly in the node editor, eliminating the need to manually copy and paste hexadecimal or RGB values. The tool supports importing and managing color palettes from external painting and design applications such as Adobe Photoshop, Adobe Illustrator, Krita, and GIMP.

The add-on can read and write a variety of industry-standard palette formats. Supported file types include Adobe Color binary formats (.aco, .acb), Adobe Swatch Exchange (.ase), GIMP Color Palette (.gpl), Krita Color Palette (.kpl), and Colormate CSV files.
