I read this once before and it's one of those facts I find endlessly fascinating. It's simple and obvious why it wasn't normal before recent times...
It just scratches my nerd fact itch I guess.
It's right up there with
And
Oh and
-we see the color that is not absorbed by an object. So essentially we see every color the object ISNT.
Your last point is more of a philosophical / semantical one. What does it even mean that something is a specific color?
It's like how blue butterflies actually don't have any blue pigments but rather have a nanostructure that interferes with light in a way that favors blue.

There are these butterflies in Central America. They're blue and orange and yellow and have poison in their wings, just enough to stop a bird heart. But the birds know this somehow, so they don't eat them. But there are other ones, butterflies, they're orange, blue and yellow too but no poison wings. They're just flying around, looking dangerous, getting by on their looks.
They know this because all birds who tried to eat them, died.
