color variable

A color variable is a visual variable that defines the color of a symbolA symbol defines the properties used to display a geometry or text.Learn more based on a numeric data value returned from a field or expression. If an expression is used, the color can be defined from a color ramp with a set of pre-defined color ranges. Numeric data should be normalized before visualizing it with color, especially for polygonA polygon is a type of geometry containing an array of rings and a spatial reference. Each ring contains an array of point coordinates, where the first and last point are the same.Learn more layers.

Color visual variables require the following:

1. A reference to a data value either from a field name, or an ArcadeArcade is a lightweight and secure expression language used in ArcGIS products and APIs. Arcade expressions are commonly used to calculate or format field values for data-driven visualizations, labels, and popups. The expressions work against data stored in data services.Learn more expression.
2. At least two color stops that match data values to colors. The colors of symbols with data values between the designated stops are interpolated linearly.
