Furthermore, there's some randomness to this. If I click only "This is blue" the hue boundary is different each time, in the end result. The lowest I got was "hue 134, greener than 100% of the population".
Same for clicking only "This is green", with the highest observed boundary as "hue 226, bluer than 100% of the population".
I clicked "This is blue" whenever a green came up and "This is green" whenever it showed me a blue. Interestingly it didn't bother with any turquoises or cyans when I did this, it only showed me unambiguous blues and greens.
At the end it told me "Your boundary is at hue 180, bluer than 85% of the population. For you, turquoise is green." Which I would've thought was impossible to discern from my choices.
