Yes, we do believe in borrowing good ideas.  In this case, we are suggesting that designers of infographics "borrow" from cartographers in carefully picking colors that do more than just brighten the page.

Color Use Guidelines for Mapping and Visualization
Cynthia A. Brewer

Click for generalized structure with links to discussion of each color scheme type

The graphic display of data plays a critical role in visualization and exploratory data analysis. Appropriate use of color for data display allows interrelationships and patterns within data to be easily observed. The careless use of color will obscure these patterns. When color is used 'appropriately,' the organization of the perceptual dimensions of color corresponds to the logical ordering in the data. The color scheme typology I present matches a comprehensive listing of the ways in which data are organized with corresponding organizations of hue and lightness.

The scheme guidelines are limited to the use of color to directly represent data that occur at locations in the graphic where colors occur. The types of thematic maps to which these guidelines apply are choropleth maps (for example, census tracts filled with colors representing the percentage of the population from an ethnic group), filled isoline maps (for example, color bands that mark set ranges of terrain elevation), and qualitative areal-extent maps (for example, different colors for different types of vegetation). My hope is that these guidelines and the associated terminology will also guide the work of people grappling with data visualization challenges in diverse disciplines such as physics, medicine, psychology, and graphic arts.

A disorderly jumble of colors produces a map that is little more than a spatially arranged look-up table. The goal of this WWW resource is to help you do better than that by using color with skill. This resource provides a generalized set of color schemes and example maps.
