Matrix row formatting (with switching values in row groups rather than columns)

I've created a matrix with three measures and changed the option so values show up on rows rather than columns. Giving me actual, target, and py. What i'm trying to do is change the color of the column/row in the following picture where highlighted. I'm thinking the answer is no because the only thing I can reference in the cell element series are the three measures for actual, target and py. If anyone knows how this can be done, please let me know. Thanks!
