Cindy Brewer: helping you choose better color scales for maps

The choice of colors you use in a statistical graphic isn't just about making your chart look good: the colors you choose are often critical to interpretation. For example, you wouldn't want to use a scale like this to represent, say, average income on a map: That palette would be suitable for qualitative data without implicit ordering (say, political...
