How To: Create or edit an algorithmic color ramp
ArcMap color ramps provide the means to apply a range of colors to a group of symbols. Color ramps are used, for example, in the Graduated colors layer symbology option. ArcMap algorithmic color ramps are a specific type of ramp that traverses the color spectrum between two end colors.
Follow these steps to create a new algorithmic color ramp in a style and edit its properties.
- Open ArcMap.
- Open the Style Manager by clicking the Tools menu, click Styles, and click Style Manager.
