How well can you distinguish colors?
The lower your score, the better.
I've done it three times. The first time, I got 0.0060. The second time, 0.0022. The third, 0.0020. Each time I went faster, spending less time deliberating and just going with the flow.
There's a running score in the upper right corner that will fluctuate as you succeed and fail. At one time, it was all the way down to 0.0005, but not for long.
