The DC Policy Center Color Scheme
Avoid red/blue or red/green contrasts; be careful with red in general, as it can impart a negative or alarming meaning to a chart. For accessibility, vary colors by light/dark and by warm/cool tones -- for instance, avoid using gray and a cool-toned color (blue, green, purple) of the same brightness.
Pie charts should be used (sparingly) to show how various parts make up a whole. Use gradients to show intensity (dark = "Very satisfied" while light = "somewhat satisfied"), colors for other categories (cities, states) Use red sparingly - i.e. to accent one of two categories. (i.e. D.C. vs rest of U.S.)
Line Charts and Scatter Plots
Use a line chart when there is a trend to show or continus data, use a scatter plot when there are data points. Use colors that will stand out from the background and axis.
