The solution is so simple you'll fall off your chair.
Just add a Channel Mixer adjustment layer and swap the Red and Blue channels ...
Red 0, 0, +100
Blue +100, 0, 0
Then mask on to the ribbons. You won't even have to mask particularly precisely in most areas.
Then, clip a Hue/Saturation layer to the Channel Mixer layer and manipulate Blues a little more if needed (eg darkening or whatever)
