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.
The next time it came up was when I needed a bag to carry something to work, and my wife handed me her bag. I complained that it wouldn't be manly to carry a pink bag to work and she told me that the bag was actually red. To me the bag looks the same color as the pink lemonade in this picture: http://janeshealthykitchen.com/wp-content/uploads/2012/07/Pa...
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...
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.
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.
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.

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 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.
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).
So I suppose a large helping of salt is required.
