>>14238874I can see in near IR and far into ultraviolet.
"Brown" is a funny colour because tree bark usually reflects ultraviolet. Those small brown 3 socket extension cords also reflect ultraviolet the same.
Mountains in the distance often have a shiny bluish haze over them.
When I loook into shaded woods on a sunny day, the contrast can be right where the shadows shine infrared.
I also get it where the infrared and UV combine to give this sort of more purple like look.
There's also a deeper UV colour, I don't know if this is alredy in the x-ray range, but it has a quality like orange if I could describe it.
