        It’s a 74. But parts of the 4 are a different shade so you see 71 if your color vision is different.

          so you see 71 if your color vision is different.

          I have mild Deuteranopia and there is no hint of a 7.

          21 or maybe 81.

            I see why you would see that for the 7. You’re relying on the brightness of the dot instead of the tint I’m guessing.

            I suspect my 5 years old to have some low color blindness, he couldn’t see the numbers in some circles I showed him.

              The meme actually uses the exact same image as the wiki page about the tests. https://en.wikipedia.org/wiki/Ishihara_test

              The number “74” should be clearly visible to viewers with normal color vision. Viewers with red-green color blindness will read it as “21”

              So at least I’m seeing what I was supposed to see!

      I just see a bunch of green and orange dots, with a small amount of tea colored dots. I don’t know what the alphanumeric scale is, I do all of my math with my fingers

    That 74 is kind of tricky and my vision is “normal”

    This reminds me of a time I was taking one of these colorblind tests. The person administering it was flipping (way too fast) through the numbers and I was reading them fine. A trickier one came up which I could very clearly read, like this 71/74 one, and I said (because fucker was flipping way too fast) “71… no, 74 actually.” He marked it wrong. It felt like a real life Seinfeld incident after that where I kind of stopped the whole test and was saying basically, as nicely as I could, “hey. I said 74. Mark that correct.” MFer didn’t even vocalize a response. I can’t remember but I think he did like two more numbers, said I passed with whatever number of tests with one incorrect. I had to get my eyesight examined after that (this was for some pilot shit. Like a physical) and I told the doctor and he kind of shrugged it off too like “you passed it. It doesn’t matter.” IT MATTERS TO ME GODDAMNIT

    Thanks for triggering this random traumatic event from over a decade ago.

    I can confirm that I see both an orange car and a 21. I’m not colourblind in the "I can’t see any colour " way and I can drive a car and see traffic lights without any problem but I do percieve colors differently enough to get in arguments with friends and family about the colour of stuff. I think it’s called deuteranomaly

      Colourblind isn’t the complete absense of colour, e.g. everything looks black and white. With deuteranomaly, you are the actual textbook definition of colourblindness… There are different levels of it, but all can still perceive colour - it’s just whether the difference in colour of the spectrum is detected correctly.

      Deuteranomaly (/ie) is the reduction in reactivity of the red-colour receptors. That means your perception of orange/red/brown is less than those with normal vision.

      For those with normal vision, this is a great chart. But, if you’re colourblind, it’ll be more confusing for you, sorry!

        Even though I know the dress factually is blue and black, I think a white and gold version should be made, because it’s pretty.

        And it should also be photographed in such a way that it appears to be blue and black.
