I know that there are devices which shift or replace wavelengths of light that are out of the visible spectrum so that we can see them. What would be the result of having a device which can sense artificial light bypass the restrictions of our eyes and send impulses directly to our brain. If our brains would even be able to comprehend these impulses, what would they look like? Would we see new colors, or somehow enhanced reds(for infrared) and enhanced blues(for ultraviolet)? If our brains couldn't recognise the new impulses, if such a device were used on a newly born child, would it develop the ability to sense an enlarged visible spectrum? And another thing. Let's say an object, a box for example, were to be created with a material which only reflected say ultraviolet light, with our normal vision would this object be the blackest of blacks and have no shadows or noticeable depth to it? Sorry I'm not too knowledgable about light so I'm not sure how much of this is theory and how much can be tested. I was just thinking about how cool it would be to see a new color, because it's impossible for the human mind to comprehend.
