      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!
