IColor Interface

Provides access to members that control the basic color interface.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

IColor is a generic interface that are implemented by all the other color CoClasses. IColor is also where transparency is managed. The other color interfaces derived from IColor interface are: IRgbColor, ICmykColor, IHsvColor, IHlsColor, and IGrayColor. You can also convert any of the color interfaces to OLE color objects by using the RGB method.
