ELI5: Why are humans attracted to certain color combinations over others?

Why do we like complementary colors so much, but not really other color combinations? For example, we seem to be drawn to green/red often.

I understand that the color wheel is the source of complimentary colors, and how they're appealing to the eye. But *why* our eyes are so drawn to these combinations versus others?

 My best theory is that when we were hunter-gatherers, contrast meant a meal (berries, animals, ect.)

The eye evolved to be sensitive to things that were beneficial to our ancestors survival. Spotting a ripe red fruit in tree full of green leaves, for example.

People actual preferences are developed over the course of their lives, but at a certain level it comes back to the eye having evolved to spot certain kinds of things, mostly related to food.
