    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!
