Simple

The default style when you upload a data layer — a single color for all features.

Categories

A categorical visualization maps a distinct color for every unique value of your chosen data attribute. A common type of categorical visualization are election maps, where a color (red, blue, etc) is assigned to every ballot choice.

When making a categorical visualization, choose between Felt’s built-in color palettes or use the Advanced Visualization Options to pick your own colors of choice.

Color range

For numeric attributes. The color of each feature will be relative to the values in its data.
