I prefer this. The failure to discus Lab and OKLab in the main link is quite odd.

Also, I'd mention to those who think that violet/magenta aren't "real" colors that the red X decays more slowly than the blue Z at short wavelengths so you can get saturated violet/magenta single wavelength colors (not well represented on the standard chroma charts) below 400nm at high power. Of course they aren't efficient for monitors (even blue isn't) and they're dangerous to look at for any length of time. But if you see a (single wavelength) violet/magenta laser, it's time to look away or shut your eyes.
