ColorBrewer
ColorBrewer is an online tool for selecting map color schemes based on palettes created by Cynthia Brewer.[1] It was launched in 2002 by Brewer, Mark Harrower, and The Pennsylvania State University. Suggested color schemes are based on data type (sequential, diverging, or qualitative). It also provides options for varied display environments, such as laptop, photocopy, and LCD projector, and colorblind safe options.[2]

[edit]
In 2018, climate scientist Ed Hawkins chose the eight most saturated blues and reds from the ColorBrewer 9-class single-hue palettes in his design of warming stripes graphics, which visually summarize global warming as an ordered sequence of stripes.[4]
