Red-green colour blindness

is this the first time you're finding out you have a level of colour blindness - as it sounds that way... You can't be "bad" at colour blind tests like you fail a math test :) You either see it or you don't and there isn't to learn that makes you better at them.

Oh I've known about my colour blindness forever, but I was curious to see how many others see green.

Like with a computer monitor, normal colour vision in humans can understand 3 colours - red, green and blue. Red-green colour blindness means that your blue vision is intact but either red or green is missing, so that both red and green appear the same. I think that if you're seeing the op's pic as green, it means that your red vision has gone, so that it makes yellow appear as green to you.

<< normal 3-colour vision here and I see yellow.

I'm sure you're correct. It's weird though because I have no problem seeing red.
 
They are yellow. If you are seeing green then yes it would appear you have issues with red.

take that test and tell us the results.

Wow thanks for the test. I know I'm colourblind but I've never had someone actually tell me what type. I did the test and got Type: Protan Severity: Strong.

You have Strong Protan color blindness, a type of red-green color blindness. Good news! People with your type of color blindness usually respond very positively to EnChroma color blind glasses.
