Here is a possible process:

-look for the bright red colour
-remove the red layer from the image at this location
-keep the green/blue layers, and replace the red one by one of the other two.

Just an idea, I use this process (with a manual selection of the area
to treat)
to solve the problem, and usually it works very well.
