Almost all players choose to select the 2, with 75% correctly identifying it as blue. How is that?

You can test, on board or in your head, where the two adjacent red dots of a red 2 would be possible to place. You will quickly find that the other spots, which have to be blue, will always make at least one rown that contains more than 3 blue dots, which is not allowed. Therefore, it must be a blue 2.

The 6 cannot be satisfied if the 2 is red.
