DEFINITION

What is a color theme?

A color theme (also called a choropleth map) is a thematic map in which administrative areas are colored or shaded according to the range in which the aggregated statistic of interest falls. Color themes can also be used to represent non-ordered data. Unlike a heat map, a choropleth map applies colors to geographic areas such as states, counties, postal codes, or other features with defined boundaries.
