Did you try a weak ammonia bath?
It clears the blue and enhances the red (which I prefer to the original brown)
Don't insist too long otherwise it will clear also the red image.

The actual brown tone was great and I have been thinking about trying again so I would love to see how you do. I tried several ways to clear the blue but nothing seemed to work for me.
