Custom shape over window

[Jaskajokunen]

Hi,

I have skin that I want to modify, and it has custom shape over and under the explorer title bar (bevel),but I cannot find how to modify the color of that element in WSB or msstyleeditor.
Can someone help me? Sorry if something goes wrong with this post I am new here.

Sorry guys, I actually just found the right attribute right after I posted this. It was shadow > top or something.
