There are not such predefined classes and the backgrounds for each tile are in only one color per skin.
The RadScheduler classes you are referring to (rsCategoryBlue, rsCategoryOrange, rsCategoryGreen) hardly change the colors across skins, a visual difference can come from the surrounding colors (i.e. appointment colors may seem brighter when on darker background, e.g. in the Black skin).
Nevertheless, I am logging this idea in our feedback portal here: ADD predefined CSS classes for RadTiles that set the background color to several predefined colors like in RadScheduler
, so everyone can vote, comment and follow it. If it becomes popular we will consider its implementation.
