Can anybody guess, would RGB lighting help a colorblind person?

For example, if a person were red-green colorblind, would lighting with
discrete RGB wavelengths help this person distinguish red from green
objects, compared to lighting with incandescent?

That's approximately the difference between fluorescent and incandescent. It
doesn't help appreciably.

In principle, if you could use spectral lines for illumination, you might be
able adjust wavelengths to selectively excite the different cones in a way
to enhance perceptual distinctions. I have not given that much thought. It
is likely to be an expensive and minor improvement even if it were all
worked out.
