Seeing yellow

Postby TheVirus » Fri Nov 27, 2009 2:35 am

hey, i was having an anaphylactic shock the other day and i noticed that at a point i started seeing everything in a yellowish tone. Do you have any idea why would this happen?

I dunno about your yellow vision..Starring at blue square gives yellow afterimage,there's blue-yellow color blindness..and there are only 3 types of cones..So how do you get yellow? There's opponent theory that says red,green,blue cones give input to the same kind of opponent neuron. You get yellow color from excitation from green and red input.The same opponent cell is inhibited by blue input and you get blue color. Another kind of opponent cell is inhibited by green and excited by red.
So you may search an answer in blue/yellow opponent neuron..
I probably didn't help..hope you'll find an answer..

Maybe it just had to do with the fact that i couldn't breathe and i wasn't getting enough oxygen to my brain or something.

You mean the anaphylaxis? Just that one time. But i've had many other less severe allergic reations.
