That was fun! Anyone knows about similar tests?
That was neat. I think the quality of your monitor will affect your results.
I did it first with a very zoomed-out screen, and quite quickly. 25 score.
Then I zoomed it a lot, double-checked each movement and position. Perfect score!
I don't know if you can extrapolate anything from that.
I had some trouble with the blue-green section, though. I've long experienced some small amount of difficulty telling the difference between very close turquoise colours, and the bar graph seemed to back that up on the results of my first test.
The first time I did this I got 44 or something but I rushed it. However on my second try I did much better lol
