Found a bunch of simulators in the process of researching colorblindness for the fic -- trying to work out which kind Jon would have, and how it would affect him. (Colblindor has a ton of information if you want to read more.)
I have so many feelings about what protanopia does to the spectrum :D The only two hues are blue and yellow, only it looks like a dirty/muddy/greenish yellow because that's what pure #FFFF00 looks like, as opposed to the warmer orange-tinted hues that we use because they're more attractive. Dark reds turn into black really fast, because the light they reflect is no longer on the visible spectrum. Even though there's "blue" and "yellow", they don't combine to make green, but grey-white, because that's what you get when you mix all the primary hues of light together.
All of which seems to imply that if a human eye could see, say, down into the ultraviolet range of the spectrum, it wouldn't just mean getting to see cool patterns on flowers and whatnot. It would mean adding an extra dimension to the spectrum as we understand it. New hues might appear between the ones we talk about, just as green would pop into existence for a protanope given full-color vision, or yellow for a <a href="http://www.colblindor.com/2006/05/08/tritanopia-blue-yellow-color-blindness/>tritanope</a>.
(So if you thought you were tripping <em>before</em>...)
