Okay, i'm not very well educated on this whole color temperture thing but i feel thta i know the basics. so if i saying something stupid please please correct me. With that said, humans see white light as white because of color correctivivity in our eyes. white light can really actually be a reallly really bright blue, green, yellow, etc. SO, can white light physically be a really really bright black. Why NO! we all cry. How could the absense of light be infinatly bright? its inherently contradictory! well, we have heard of black light.... can we take black light to the extreme? have we already done that, and are now using it somewhere in science. I'd image it requires a heck of a lot of energy input. so, the human eye can't see UV light, but in technicality, ultra intense Uv light could infact be white? To answer this we might need to adress the definition of white light, or of electromagenetic waves in general. is white merely the resulant of of a certain wavelength?
