Hi,
This might be a little bit left-of-field, but is there any way of measuring the degree of someones color-blindness (etc) then superimposing that inversely as a color-profile within a given piece of software (or monitor calibration)?
Like when someone has a frequency-based deafness and they get hearing aids with their own personal eq supplimentally hardwired into it. If the same principles as they use for aural problems could be applied to vision, say, calibrating a color-blind persons monitor with a profile based specifically on the users particular spectrum-based visual impairment, then while not a perfect solution, might still be a way of giving someone a 'flat' view of all colors as an unhindered pair of eyes would see...
I don't really know anything about what I'm talking about... just a rambling idea...
