In classed choropleth maps, different colors are chosen to represent different degrees of a category. In unclassed choropleth maps, differing degrees of a value are represented on a continuous color scale that gets darker to represent higher values of the category. The above image shows the fertility rate attribute values for countries in Europe. The maximum fertility rate of 2.27 children per woman (Albania) is represented by the darkest shade of orange, while the lowest rate of 1.13 (Bulgaria) is represented by the lightest shade of orange.
