It's quite possible she could see some of those colors in real life if you had access to a light-source with "adjustable spectrum". Think something like an RGB

It's quite possible she could see some of those colors in real life if you had access to a light-source with "adjustable spectrum". Think something like an RGB lamp but with more colors/wavelengths, and adapted to her particular spectral response. Having built a similar kind of lamp myself, I have to say it was quite wild even for a boring old trichromat as me!
