ColorBrewer is a set of carefully designed color palettes for maps and other graphics. It was originally created by cartographer Cynthia Brewer in the early 2000s at Pennsylvania State University to help mapmakers choose colors that work well together, reproduce in print, and remain readable for people with color-vision deficiencies. Over the years it has become a standard reference for selecting sequential, diverging, and qualitative color schemes. This project will extend and modernize the tools for web cartography and GIS.
