Running header/footer background color from XML attribute

I'd like to set the background color of running headers and footers, based on an attribute from an element in my imported XML-file.

Basically what I want is to have different colors of headers or footers for different chapters in the book (catalogue).

Is there any way to do formatting like this from the EDD or rules? Or is there some other way to achieve a similar result?
