Hi guys. Long time lurker first time poster.
So this might be a long shot i cannot find it and i'm pretty tenacious. It's not in msstyle file as far as i can tell. I opened shellstyle dll in resource hacker, don't see it as an image file in there either. I figure if anyone knows it will be someone here. The blue white gradient. Appears on applying attributes and processing pane.

Thanks in advance for any help.
