Assembly: System.Design (in system.design.dll)
The BuildColor method starts a user interface for selecting a color value.
The ColorBuilder class is not intended for use outside of the design time environment. ColorBuilder requires the IWebFormsBuilderUIService, which is typically available within a Web Forms project at design time. If you want to build HTML color strings, you may want to implement a method that converts the RGB values of a Color object to an HTML-compatible RRGGBB format string. If you intend to use a control to select a color or configure a color, you can build a user interface for this, or you may want to use a PropertyGrid control which allows you to edit Color properties with the default ColorEditor providing a color selection interface.
