RadColorDialog provides full localization support. See Localization and Right-to-Left Support for the full list of Telerik UI for WinForms controls that support RTL languages, layout and localization.
The control is shipped with a rich set of themes that allow you to easily build slick interfaces with the look-and-feel of some of the latest Windows and Office versions. The themes can be easily switched using a single property.
Our framework also features support for custom themes, which can be built from scratch to fit your exact visual demands by using the Visual Style Builder productivity tool.
