Color vision in mammals is an interesting subject. Having a personal reason for getting involved with it should not be discouraged.
Just as researchers have studied ultraviolet images through photography, red/green can be studied the same way.
Not only that, but the research papers are normally written as ordinary text. Should the occasional color image present itself, the technique I described above may help in deriving information from it.
However, I wouldn’t get my hopes up just yet about gene therapy. An experimental technique on laboratory animals is not indicative of a solution “just around the corner”. Lab animals usually have very short lifetimes, and some of the problems inherent in gene therapy may be masked by the shortness of those lives, even when they only die of old age.
