I have often imagined the existence of some such software, but i have never heard any mention of it.
My own best technique has been to avoid problem situations as much as possible (and to get my wife, who has normal color vision, to critique my prints as needed.)
Until a few years ago, my own photography was 90% black-and-white. I shot some Kodachrome and sent it to Mother Kodak for processing. If any colors were wrong, I could blame it on the film or processing. When I first started playing with digital, I was delighted at how easy it was to make color prints -- and how easy it was to screw up the colors beyond belief. What I do now is the following:
1. Convert many images to B&W, whenever the color isn't essential to the image.
2. When the color is important, and the scene wants to be believable or realistic, I use either the "as shot" or "daylight" color balance when converting from raw, and never touch the color temp sliders or play with saturation or hue. I can't trust my eyes, so I leave it alone.
3. Some of my color images are sufficiently abstract that the actual color doesn't matter. In that case, I feel free to play with colors, saturation, etc., until I get something that appeals to my own peculiar eyes. I know it will look different to others, but often it seems interesting to them, too.
4. I generally avoid portraits in color, and when I do make them, I carefully follow rule 2, above. I have some small group snapshots done several years ago in which some of the faces are purple and others are green, even to my eyes. This resulted from my own attempts to "fix" the original image.
So: you have my sympathy.

P.S. I have also worn hearing aids for about fifty years, but I play flute in a small klezmer band. Don't let any handicap get in the way of doing what you like, if at all possible!
