  "Description": "Automatic generation of maximally distinct qualitative\ncolor palettes, optionally tailored to color deficiency. A set\nof colors or a subspace of a color space is used as input and a\nfinal palette of specified size is generated by picking colors\nthat maximize the minimum pairwise difference among the chosen\ncolors. Adaptations to color vision deficiency, background\ncolors, and white points are supported.",
