hella weird!
I never heard of a person only able to see in black and white.
I've heard when you cut yourself when you are x meters underwater your blood will look green because after so many meters under the light doesn't penetrate the water enough for the red spectrum (which supposedly is on the outside) to come through. Making the colour red, green. Or something like that.
I messed up a lot of times buying paint for my house though. "This looks like a nice shade of white" go home and start painting and everybody full laughing because it turned out to be pink instead of some shade of white lmao.
breh many years ago I ventured off to go clothes shopping by myself ( big mistake but that mostly why I wear black ) & I was going on a date that night...
my neighbor comes over before I was going out & I had just got dressed, & he tells me "you realize that shirt is pink, right?" Im like hella nah, the bitch at the store said it was blue.
turns out it had slight blue & purple stripes on it, but the shirt was pink.
pissed me off cuz i paid 80 bucks for a punk ass homo shirt.
