  Could also be called display quality quiz

  30 and 1 error, that last one of all purple I just couldn't find it.

  I'd bet that monitor panel quality might a big difference.

  Edit: Of course, the end text was funny because it said I could spot a mosquito a mile away, which I think has nothing to do with my color accuracy. I wear prescription glasses.

  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 vision, one would suddenly jump out...

  17-20 depending on the colors. A lot of them were immediate but the dark blue/purples were difficult.

  Was it just me or were all of them lighter? Were there any where the color was darker than the rest?

  Just curious if that makes it more/less difficult or has any effect.

  Squinting did help occasionally. As well as going with your gut usually. Fun way to spend a few minutes.

  Edit: Sadly I couldn't score less than 1 since clicking the wrong color doesn't start it.

  Everyone should also compare monitors, browsers, and OS when saying what they got. First try: 31 / iMac 5K / Chrome. [edit: regarding browser, I don't know much about color profiling, but I do recall seeing an example of the same images being rendered in completely different colors across different browsers on the same OS. Can't find a link.]

  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.

  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).

  I don't understand the timed component. I can score 100% on this one:

  But I ran out of time after getting 12 correct on the linked test. Edit: managed 28 after repeated attempts. I feel there is some luck of the draw here, depending upon which hues follow which previous hues, and the placement of the correct square.

  I scored 33.

  I found squinting my eyes made it easier to spot the "blob" that had the wrong colour, and this technique made the game a lot easier.

  8 then 30 so there's not much science here

• by sethammons on 6/19/15, 5:46 PM

  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).

  25 on first try. But then they go and compare my vision to a hawk, saying that I can somehow see a worm in a tree... which wouldn't have as much to do with my ability to distinguish color as it would my ability to discern detail at distance.

  So I suppose a large helping of salt is required.

• by jnordwick on 6/19/15, 4:04 PM

  25. Hawk. I felt like i was guessing on the last few but somehow they were correct.

• by spacec0wb0y on 6/19/15, 3:56 PM

  Strained my eyes doing it, had to look off into the distance for them to feel normal again! But got 31 which put me up over 95%. Think the peripheral vision trick helps in some of them.

• by fruzz on 6/19/15, 5:09 PM

  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.

  Speaking of vision, if my finger gets slightly blurry when it's less than three inches from my face, does that mean I need glasses?

• by kanche on 6/19/15, 4:33 PM

  33 with 2 errors. In the last ones I was seeing optical illusions - black dots were appearing at the white intersections!

• by bshimmin on 6/19/15, 4:55 PM

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

  3. Beat that.
