Comment on Ask HN: How do you deal with color blindness?parent

Comments

you don't have a colourblind person's 'profile'

Why not? As far as my understanding of color blindness goes, you just need to find a precise transformation matrix and offsets to be able to correct any type of deficiency (except for achromatopsia, I guess).

When I use them I find the colour profile I am used to in the wider world flipped, and the semantic meanings given to colours, or their hierarchies, completely changed.

I think the correction applied to digital content is a positive thing. At once you can perceive color the way it was intended to be perceived. May be wrong here because I don't have daltonism.

You can try to make a perfect system for every variation but the end user won't see it as precisely as you intend.

My goal is not cover every case, but to create exactly one profile (and perhaps create a usable correction workflow for someone else)

Thanks for an elaborate response :)
