>correctness is not the point. binary choice is the whole point. because my blue may not be your blue...

Realistically there is a broad range that we all can acknowledge is neither, but is instead teal, and forcing a binary choice means people just choose randomly.

I don't think that's necessarily the case. I understand that there's a continuum in reality, but psychologically, I still tend to perceive each shade as discretely either blue or green, especially when the shade is presented in isolation. Words like "teal", "cyan", etc. aren't really part of my normal vocabulary and to the extent that they are, I would think of them as subsets of blue or green, not disjoint sets.

I think the test can be fairly criticised on the basis that it is assuming everyone's psychological colour space has a discrete boundary between blue and green, which clearly isn't the case for some people (like you), but it is for others (like me).
