The attempted point being to measure and compare how people classify colors between blue and green when given a false dichotomy between the two.
But it cannot do that without bias, since people always have the third choice to drop out when they don't like their choices. There is also another bias, which is people will just select some random option when they want to say something equivalent to "blue-green" but don't have the choice, then they get a result biased in that direction but what has actually happened is they have given up. This random choice might be culturally biased towards people's preferred color. I personally selected green when that occurred for me and then just sat on green hammering that. Oh, I'm more willing to say green than other people? Meaningless, I wouldn't have called those colors green in a conversation.
When presented in a forum people also have the choice of criticising the false dichotomy which is what you are experiencing here. The point of posting it here is to get this sort of feedback, so...
Conjecture is precisely why you don’t understand the test. Bias is the point! Binary choice is how you derive it. No answer is not an answer. How do you not see this? Any conjecture on anything but the two options defeats the entire point of the test. The test is to find your bias towards blue or green. Cake or death.
