Overview

About

Maintained by Jakub NowosadFirst published 2021-09-093 releasesCRAN page ↗GitHub ↗

Compare color palettes with simulations of color vision deficiencies - deuteranopia, protanopia, and tritanopia. It includes calculation of distances between colors, and creating summaries of differences between a color palette and simulations of color vision deficiencies. This work was inspired by the blog post at https://www.datawrapper.de/blog/colorblind-check.
