Which also means that you can’t see it on any computer screen, so any image you find on Wikipedia or anywhere else is an approximation.
Is it possible/likely that someone with dichromacy and inoperable L cones would have already observed this color? Or would they need to have tricolor vision to learn to perceive it?
I read that people with monochromacy only perceive grayscale which implies that the brain needs the three types of cones to map out the colorspace.
