ELI5. Why mixing colours give us other colours. Like what’s the science behind?
In: Chemistry
It’s just how our eyesight works. We have three types cells in our eyes which are triggered by red, blue or green light correspondingly. Different combinations of these basic colors produce perceptions of different other colors. Other animals (like birds) have four types of color receptors in their eyes, so they are much better at discerning various color combinations. And in fact some rare humans (mostly women) are also tetrachromatic, giving them better color vision.
