How Do I change The Color of the White Start Button in the Win7 WindowBlind called "Windows 8 Metro?

Please don't be confused...I am not asking a question about the Win 8 operating system. I am asking a question about Win7 themed skinss

I am so frustrated...I dont like the White Start button that comes standard on the "Windows 8 Metro"windowblind for WIN7, Vista and XP

When you apply the "Windows 8 Metro" Windowblind, as you know the taskbar is black and the start button is white.  When you hover your mouse over the start button the color changes to the normal multicolored win start button. I don't like the white. 

I know you can change the Start Button properties in Skin Studio..I have tried, but I guess I am stupid because i don't understand the very minimal instructions they give you to make the change. Can someone explain how to get rid of the white color permanently...i.e. so the button is always multicolored?

Thanks,

Warren
