      My dad is red green color blind. I just showed it to him and he couldn’t read it.

        There are differing scales of deuteronopia (what red/green color blindness is called). The more overlap between the ranges your red and green cones’ wavelength reactivity, the worse the colorblindness. Mine is not super bad, just enough to be annoying sometimes.

          Also, protonopia, further adding to things.

          ‘red/green’ means either you have difficulty seeing red, or maybe green. Then there is severity. I am evidently relatively severe protonopia. Like if you take a picture and just delete the red channel, I can’t really tell except if there’s some extremely pure red in it not mixed with anything else. Any hint of other colors in the mix will drown out any red perception.

      It does appear that it’s a red/green color blindness thing, but perhaps the camera picked up the colors slightly differently than it would actually appear in person.

      So, even though you can manage to read it on your screen, you might actually not be able to make it out in person. 🤷‍♂️

          Note that I did a shift to see what it should look like, shape wise, if you can see it.

          here

          I cannot make it out, at all, in the original picture. But it’s clear it shouldn’t even be slightly obscured/hard to trace after a shift.
