ColorBrewer Intro – Selecting Good Color Schemes for Maps

One of our listeners, Jody, emailed us a link to ColorBrewer, an online tool to help people select color schemes for maps. It uses a flash-based map to demonstrate how changing colors affects the look of a map and how that impacts the information being represented. It’s a nice tool to give a user an introduction to choosing colors for maps, so they can immediately see the visual impact of their choices. Cynthia Brewer, the Penn State geographer who designed the ColorBrewer, has also written the book Designing Better Maps: a Guide for GIS users.
