Doesn't it piss you off? :D Human beings can only see such a tiny little portion. Eagles can see in to the UV and IR which to them, I mean, who knows what they can see, I bet everything lights up like a Christmas tree. They can probably see radio waves and clouds of natural and unnatural radiation for all we know.

With IR

With UV
Those are minerals from wikipedia under UV light which is considered "near UV". So you can imagine how strange everything would look. A lot of animals and flora evolved to take advantage of it since they can see in that range, sometimes they can only see in that range.

Seeing in the infrared also means you can "see" heat, so heat emitting from an animal for example would literally glow.
I cant even imagine what the world would look like if we could see every part of the spectrum of light radiation. We'd probably go insane. Even sound would disturb the image, you'd witness the movement of air as it swirls in different temperatures and levels of microbe, rays of all refracted and reflected light would bombard you and the radiation given off things naturally would glow like highlighted objects, your own body would be phosphorous in its description. Every wave of and band of radio and projected frequency, you would even see the radiation of living and nonliving things regardless of of your eyes being open or closed as x-rays would penetrate everything unless it's too dense, like Superman. We'd need muscles in our eyes that dont exist to control the level of input because i'm pretty sure you'd never be able to actually see a single object or focus. It pisses me off that we can never see what an object truly looks like. I also always wondered what colors look like in space outside of the atmosphere without NASA retouching it.
As far as cultures that thought green was blue, do you mean the writings of the Aztecs that suggested that they all had an inherited birth defect resulting in color blindness? or the prolonged exposure to the sun in your African and South American cultures, that can cause several types of blindness.
