Could also be called display quality quiz

Yep. I got 36... on my 27" Dell color-calibrated display.

This is super easy if you use Digital Color Meter on the Mac!

I get that the threshold for just-noticeable color difference is much lower if the tiles are touching but I found the Hermann grid illusion that arose from using spaced-out rounded squares to be very distracting.

I'm partially colourblind (deuteranomaly), and stopped after I hit 30 with 0 errors. I normally do very poorly on Ishihara or Farnsworth-Munsell tests.

I got 23. I know I'm a typical "partially color blind" male, e.g. I always fail those tests where they show you an image made of a bunch of colored dots and ask what number you see, but on this test, I found I could find the outlier much more easily by using my peripheral vision: staring directly at it the grid, all the squares would look the same, but by looking to the side and sort of scanning with the edge of my v…

27 here ("Wow, you have excellent colour vision.") with fairly typical red/green colorblindness. I also fail the the Ishihara plate (dots) test like clockwork.

Does this test different hues (or brightness even?) of the same color rather than the red/green blue/purple of the dots? (Can't tell myself, am after all colorblind.)

This test seems to be about something else rather than traditional colorblindedness.

Is it a _color_ (~hue) test a lightness test? I see changes only in the later (and then it would make sense that some of my color-blind friends make reasonably high score).

SCORE: 30 ERRORS: 0 Better than 90+-someodd% of the population.

I found purple hardest. I eventually failed on a purple.

Reminds me of http://www.xrite.com/online-color-test-challenge. I believe I scored 97-percentile on that (a 3).

3. Beat that.

Did you notice it in your daily life before this test? I got 29 first try. But I'm sure some people get much higher. On the other hand, my hearing isn't great though. I wonder if it's related.

Nah. I was just being a jerk. My first attempt I got a 31, my second attempt I got 19. My third attempt I was sick of staring at colored blocks and my eyes hurt so I threw the game at 3.
