Setting Theme Colors based on RGB Values in the active workbook

[MssbrgMn]

I'm having trouble finding a solution to this problem. Basically, I build a bunch of workbooks for colleges and I like to have the colors match the school colors as much as I can. I can make themes for each school, but eventually I lock off a bunch of formatting functionality, so the end result is making a new workbook for each school. Ideally, I would like run a vba script that changes the text/background light 2 and text/ background dark 2 to RGB values in the workbook (that way I can just change those as needed rather than make new themes for each organization. Any ideas? Thanks a ton!
