I got 83, and I'm not colorblind whatsoever, my vision is 20/25.
wtf.
I don't think it really has to do with colorblindness. If you're colorblind but still have good eyesight then you can probably tell the different shades apart just fine, they just won't look the same as everyone else.
Either you rushed through it and didn't look very closely, your monitor's contrast it too low, or maybe you're eyes just aren't as good as you thought
this is bullstuff, they're all way too similar.
Uhh
then that probably means your eyes are bad
