Me and my friend invented a color called orangutan in 1-2 grade. We had different variants of it including McDonalds orangutan. Basically just a bunch of colors mixed together, and to make different variants we’d add certain colors. For McDonalds orangutan we just added extra yellow and red
Aha...Yea.
Also Tetrachromacy is genetic condition (if you can call it that) where someone can an extra cone (or was it a rod) which allows them to see colors better. Just like birds which can see ultraviolet light, but that's an example of that
