MetBrewer
Color palette package inspired by Metropolitan Museum of Art in NY
...The palettes are curated, named after artworks or styles, and often include notes about colorblind-friendliness and contrast. The package supports both discrete and continuous palette types, with interpolation when more colors are requested than originally defined. It also provides ggplot2-friendly scale functions (scale_color_met_c, scale_fill_met_d, etc.) so integration into typical R plotting workflows is smooth. Internally, the package includes functions to list available palettes, check which are colorblind-friendly, and visualize all palettes at once.
