Mysteries of human vision

So, as you may know, this blog isn't necessarily "out of this world". Sometimes I write about things that are more "down to Earth". So, let's explore the mysteries of forbidden colors- what are they? You can read quite a lot about this mystery here.
What's interesting that I've once read about is this girl who has a really good talent in painting. She doesn't paint in forbidden colors, however, she paints with intriguing combinations of colors. The scene doesn't look the same to a regular person as it does in the paintings. The paintings are more vivid. It's thought that she sees more colors than a regular person. In other words perhaps, she doesn't see purple as we see it, but actually has purple receptors.
Blite (Black-white)
You heard right. I've had such a vision. This one, however, is one where you can forget about eye tracking. I close one of my eyes & with enough experience, the view from the other eye starts to get filled in with static. I'm unsure if this is exactly Black-white, but I'm sure it's quite close.
Seeing into the future
Could we someday be able to create goggles that let us see other stuff too. For example, goggles could let us see temperature, or sound? So maybe here on Earth such technology wouldn't offer us much, but now imagine looking at the night sky.
You most likely can't see UV light
A normal human being doesn't have the ability to see UV. However, when it comes to people, there are some, yet rare, exceptions. Some individuals are able to detect UV-A light. In the past, & perhaps in today's world as well, when people would go into cataract surgery, mistakes were quite possible. Sometimes the portion of the eye that protects against UV light would be damaged. So, the patient might then see the world slightly differently than others. This ability has been used in the past in the military. People with this ability would be used on ships. Ships would issue light signals using UV light so enemies wouldn't be able to notice, & the observer would signal others as to what the signal's message was. The effect of such vision on an artist, for example, would be that a painting would be more blue than what a normal artist would recreate.
