Just to propose a different point of view, color vision in humans is caused by the response of cone cells, of which we have three types: L, M and S. Now interestingly, according to Wikipedia:
The first responds the most to light of the longer red wavelengths, peaking at about 560 nm. The second most common type responds the most to light of yellow to green medium-wavelength, peaking at 530 nm.
Meaning that our “red” cones respond better to yellow light than our “green” cones.
Yellow is far closer to red than blue… it has a wavelength of ~570 nm, while red is ~615 nm and blue ~470 nm.
Edit, mistake
This is like saying that I’m closer to being a New Yorker than a Californian, because I live in North Carolina.
Sure, something is “closer”, but it is completely distinct and has little to do with either.
But that’s only in RGBW, how about in CYMK?
