As someone with this genetic defect, and who has also been a graphic
designer for a living, I think you are right and also wrong. Yes, a
color remapper would be a simple solution. But the problem is not the
remapping technology, it is the map itself. You have to know how the
applications designer is intending to use color. Are they using a
linear path across the hue spectrum to indicate a continuum of values.
If so, then if you remap to a linear path across a grayscale, it should
be just as usable. But if the designer is using societal conventions
(yellow warning signs, red stop signs, green go lights,
etc.) then you've just screwed things up worse. So you might end up
with a different map for every application. And there might be some
applications where you need a different map for every screen change!
Most color blind people don't want to spend their time building color
maps all the time or even switching between already made ones.
Certainly I don't and I am much less of a computer phobe than the
typical appliction user.

As it turns out, I am also deaf in one ear. Largely I don't care if this
is called deaf or acoustically impaired. Similarly for being called
color blind. However, there are times when greater precision is helpful.
If I say I am deaf, many people try to avoid giving me information
orally and try to put it in writing. The term deaf implies to them the
hearing--whereas in my case it is merely anomolous--I might hear some things
(those close to my good ear) and not others (those close to my deaf
ear). So instead having everyone write things down for me, I adjust
where I sit so that I can hear what I want to hear and ignore what I
don't want to hear (its great when trying to sleep in a noisy
environment!). Also, I can't identify the location of a sound as well
as other people, so I am more cautious than most people when I hear a
siren while driving. But other than that I basically get along quite
well in a stereo hearing world by adjusting myself and not people and
things around me.
Similarly, for color blindness--hue intensity anomoly would set
expectations for others better. I can see colors, I just see them
differently and I have enough ability to work around my anomoly that it
isn't a big problem. At least it wasn't so big that it prevented me from
founding, building up and selling a successful graphic design business.
So call me color blind if you like; I don't care; but you don't need to
get too helpful by overinterpretting the word "blind" to mean total
absence of hue discrimination.
