Where to set default glass color in msstyle?

[sebaz]

In the .theme file, I know how to set a specific color for all the aero glass areas (the areas that are modifiable using the Windows Color control panel in Windows). The problem is, if I'm working in W7SB and I click the Test button, it defaults the glass color to the ugly light blue MS set as default, and that makes me waste time because I would have to go to that control panel and set it again to what I want. Is there a way to set a default in the msstyle file that I'm working on? I saw there is a property that starts with "Colorization..." but when I change it to my Colorization code it gives me an error, and even if I leave it there, it doesn't change it to my color.
