help Cynthia Brewer FAQ
What did Cynthia Brewer create ColorBrewer for?
Cynthia Brewer created ColorBrewer to help cartographers select readable color schemes for thematic maps. The web tool distinguishes sequential, diverging, and qualitative data and lets users test schemes by class count.
What is the difference between sequential and diverging ColorBrewer palettes?
Sequential palettes show ordered values progressing from low to high, while diverging palettes emphasize departures on both sides of a meaningful midpoint. Qualitative palettes are intended for categories that have no inherent numeric order.
Does ColorBrewer identify colorblind-safe map palettes?
Yes, ColorBrewer can filter or flag schemes for properties including color-vision accessibility, printing, and photocopying. Those checks are one reason its palettes are widely used in GIS and data-visualization software.
Where did Cynthia Brewer teach cartography?
Brewer was a professor at Pennsylvania State University in the Department of Geography. Her research and teaching connected map design, statistical mapping, and the practical use of color.
