Tradeskill Window: Create Page :Progress bar colors

I tried playing around with the tradeskill xml to get the progress bar colors to change but I had little luck.
If anyone has done this or knows how please let me know. I tried simply replacing the Color="#XXXXXX" with the 2 colors I wanted, but no such luck.

I've tried playing around with the various settings and while I can change some of the colors.. I'm unable to modify the colors on the main bar at the top of the window.

any help or hints would be greatly appreciated.
