That might apply to built-in faces but less so for third-party packages. One could argue that this is a deficiency on their side (and it is) but a general solution should handle that, too. And it's not only a matter of colors versus no colors. Someone who is color-blind usually can't disambiguate red from green too well but still she might enjoy colors, just not combinations of red and green in the same buffer. (Well, of course replacing shades of green with an alternative color that is properly distinguishable of other used colors is a much harder job than just stripping colors, but at least it seems doable.)
