I'm colorblind (actually color-deficient -- I have less contrast between specific shades in some parts of the spectrum, so that I can see less of a color range than most people.) There are software "photo-filtering" programs available that allow me to "simulate" what I see. I ran a few photos through that software to show my wife, and her impression was that the "filtered" images looked "washed out". She says she definitely wouldn't want to live with my kind of vision, because it just doesn't look "complete". Comparing this to Geordi, who can see a much wider range of the spectrum than most humans, due to his Visor. In short, he can see a lot of "colors" that aren't accessible to most humans. But in Nemesis, he gets the chance to see with normal human eyes for a short time -- and he loves it. I don't get it. From his perspective it's like he's suddenly seeing with the most massive colorblindness filter in history. If I were him I'd be scrambling to get my visor back!
