Now I recall I never understood mixing of primary colours when they are lights.
And now it strikes me as strange I never wondered why printer ink was magenta, cyan and yellow before today and not pigments red, blue and green. hurt my brain.

@River You think thats weird, what is really weird is the colors we see are mostly lies. Two colors that look identical to us can be completely unrelated to eachother.

For example two things can look green, indistinguishable. But one is in fact a mixing of blue and yellow light while the other is pure green (a single frequency).

Cooler yet if you take those two items and put them under a light that is itself pure green then the pure green object would look green and the blue+yellow form of green would look black.

If you ever have colored lights play with it.

@freemo I just watched a YouTube video on this but that used red and green light to make yellow. And then split it up again with a prism. Our eyes can’t tell difference between the pure yellow and the mixed version. It is all very strange. But my confusion over this made more sense why friend was convinced Green and yellow made blue, it isn’t very intuitive.
