I’d LOVE to graph in LAB 3D mode the visible range of colors of the standard eye.
I don’t care whether it’s thousands of graphed dots that form a shape, or an actual ICC profile.
I found CIERGB.icc on my system, but can’t find much information on what it is. Guessing it’s for the CIE RGB triangular area defined in 1920. That leaves out a lof of saturated greens and blues, in particular.
Found a D50_XYZ.icc from color.org, but it’s large. (ProPhotoRGB large.)
I’m happy to generate a bunch of random numbers representing colors… If there’s a way to test a particular defined color as to whether it’s visible or not.
