ColorBrewer


ColorBrewer is an online tool developed in 2002 for selecting thematic map color schemes based on Brewer's palettes. The ColorBrewer palette found uses outside maps, such as climatologist Ed Hawkins' choice in 2018 of ColorBrewer reds and blues for warming stripes graphics portraying global warming.
