I have tried creating skins based off of "simple" and "web20" doing my best to get spacing correct with these clunky controls. And then using images for backgrounds on the menu and hover items. However when I add it to visual studio and view- my images are completely overridden with the base colors. My images don't get processed at all. 
The odd thing is- I remove all references to these color, yet when the telerik builder compiles the css it puts them back in.
I am focusing on the menu item (635 lines of css? Really?)
Here is what is created.
