Find out if you are red-green color blind like myself.

(Granted, various monitors display colors differently, this test may not entirely accurate, although for me it was.)

I'm not color blind, I think I would have known by now. Does that mean you can't see a difference between red and green? Too bad, green is a cool color

I'm not color blind! I almost thought I did for a second, but I am sitting in the dark and have been staring at this monitor non-stop. That might have something to do with my impaired vision.

I'm not colourblind!!! Whoohooooo! >)

People who have a certain colorblindness are not oblivious to those colors they simply can't differentiate between certain colors.

Which would mean you see one color in it's place, right? Like you'd see what I see as red-green for red and green?

 

[Misanthrope]

what if you can tell the numbers there but just barely?
is there like either you are color blind or not or are they shades of grey to it?

 

[Obyeybyeogone]

Some of them are definintely hard to see, but as long as the number you can barely make out is what the key says, you should be non-colorblind.

Not necessarily, if I were looking at two different colors, I might still see two different colors; they simply might be different from (in any number of ways) someone with normal color vision. Then you can ask, what is normal color vision? It is impossible to convey precisely. Obviously no one has the same perceptual experience.

Oyo, tring to get S4R to clearly and adequately explain his color-blindness is like pulling teeth. I never get a satisfactory answer.

The question I'm always left with is this: He'll say he sees a green traffic light as what I would call white. But how does he know what white looks like through my eyes (i.e., to people with "normal" color vision)?!?! And how did he even discover that he is color blind? Like, how come he didn't just think that green is white?

Oh my god, my brain hurts. This topic frustrates me.

Well apparently im still colourblind

although i could barely see one of the numbers i was supposed to be able to see, and i could kind of see two others (i couldnt tell what they were but i could see some basic number shapes)



A completely colourblind person sees in black and white.

People who have a certain colorblindness are not oblivious to those colors they simply can't differentiate between certain colors.

Even though you dont realise it you dont see as many colours as normal people. If normal people saw the exact image through your eyes as you see then they too would not be able to tell the difference. Thats how those numbers work, a normal person sees two distinct colours and can therefore see the number which is made from a sligthly different colour. We on the other hand see all the dots as the one colour (im ignoring how there's different shades and stuff here) and so dont see the number.

All humans see in 3 primary colours: red,green,blue i believe, same as the monitor (which is why it can create all the colours we can see with only 3 different colours!). I think a colour blind person has problems with one or more of the sensors in the eyes that detect colour, it doesnt mean they wont see red or green at all, but what they see will be limited. As i said, a totally colourblind person sees in black and white (though i doubt they've proven it, this is what they say) because they detect no colours with their eyes, but the eyes have other sensors (i think im talking cones or rods or something, but i dont know) and so they see only light/dark.
