…if only they would switch to CIELAB…

modularising hue functions in a mathematically/sensorially/algorithmically elegant/artistically knowledgeable way is a line item on the civilizational complex phase portrait to-do list, and is difficult because such functions are brittle

Why do you say that? CIeLab is based on measurements of the numbers of cones, which don’t change in just a few generations.

because there is not just CIELAB to consider. Maybe I want something which is Nevanlinna theoretic sensitive. Maybe I want an impressionistic filter? Maybe the display device has a strange color model.

People have more green cones, that’s independent of the usage

what if the user has red-green color blindness? or tritanopia?

Replying to @isomorphisms
my point is that CIELAB doesn't solve the /modularising hue function/ line item: it's larger and somewhat more atrocious a problem but kind of silent. and... if we have lots of people using the same hue function at least we can see where sixth roots of unity are.

and the software they have may not make using CIELAB easy out of the box?

Replying to @graveolens
I think this is the central issue. It’s easy in R (and I thought in python? and matlab?). But if not, you’re right, it would create confusion across plotters…
