      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!

              so with your 21, do you actually see a colour difference between the numbers and the circle or is it a brightness difference?

                Yeah, the number is in green and the background circles are light brown to beige.

                  That is absolutely fascinating as I can’t see any hints of a 2 or how what I see as 7 becomes a 2.

                    I think I found the 2. Look at the 7 again and slightly to the right of it. The background dots are colored slightly darker brown compared to the rest of the background. Trying to focus on these brown dots instead of the green 7, you can make out the slightly shifted 2.

                    Didn’t see it until many people here referred to a 2.

        I can see it, but only when I look at it real hard, if I just take a glance it’s 71 for me. The different shade that part of the 4 is made of really throws me off for some reason

        So to get this straight, I see the other green but it’s like a sludgy brown-lime green as compared to the full on greens. It contrasts so much from the full greens that you actually have to look for it rather them glance.

        Is that how it’s designed to look? Because if so it’s less a test and more a trick. Otherwise I may have learnt something new about myself

        You guys have to be memeing. I can sort of see the 4, although it’s pretty subtle. But there’s no way that’s a 7. It clearly curves at the top, like a 2.

        Edit: Ok, nevermind. I just loaded up the image in an image editor and shifted the hue a bit. I can see the 74 then. I knew from previous color vision tests that I had somewhat less than average color vision, but I didn’t think it would be this striking.

            It’s really not that bad. There is a good chance you can go through life with a mild red/green blindness and never notice it.

            I only learned that I had it when they did the medical exam for joining the Army. And the only other time it effected me was during shop class, when I regularly used the wrong electric resistors when building my circuts, even though all my drawings and calculations where correct. Well, they are very small and colour coded with just the wrong colours … but I only figured that out years later when I got my diagnosis from the medical.
