I think the alternative should be "this is not blue". I was served what I would call a "teal" or "turquoise" but the alternative button shows "this is green", which it was not.

I interpreted the buttons to mean "this is bluer than it is green" and "this is greener than it is blue".

When the final threshold image was displayed, I felt that the boundary was too far over to the left and I had a fair amount of green on the blue side.

I think this would work better if the hues jumped around a bit instead of blatantly triangulating, so that you wouldn't be biased by your prior semection.

That is the point of the exercise though. Is 50% really where you draw the line?

But the point is, there is no line which separates white and black (or green and blue). 50% grey is neither black nor white, it's grey. Turquoise is neither green nor blue, it's turquoise.

but when does turquoise start and end and green starts and blue ends? or is there just another color there between them. And then what about that color?

I see it as having a blue component and a green component. If the mixture has more green than blue, then it's green.

The analogous version in black and white is "is this dark grey or light grey?" because that's the one asking you to guess which side of the 50/50 split the color is on.

The other week my wife and I were disagreeing over whether a house was green or blue. I was shocked when every passerby we asked agreed with her that it was green. I was absolutely 100% sure it was blue. Turns out according to this site, my boundary is greener than 95% of the population! Funny to see this proved out here!

In the sitcom Mad About You there is an episode where Jamie tells Paul to put on a tie. Specifies the "navy blue one". "I don't own a navy tie." "Yes you do, it's the one that you think is dark green."

My wife and I go round and round about what is and isn't blue and/or green.

One thing that I find interesting when thinking about colour perception, is that even if two people agree that a given colour is red, there is no way to know (as far as I am aware) that they actually perceive it in the same way. Maybe the brain of one person paints it red, and another paints it differently, and there is no way to know as we can't get into other people's heads.

That’s assuming that there is something like a “true” internal color that external colors are mapped onto. I think it’s more likely that for the brain, “red” is just “that hue signal range that red things have”. Which is roughly the same for everyone (modulo color blindness), in the sense that if one person sees two objects as red, another person will also see them as the same color, and will perceive the same brightness and hue relation relative to other objects with adjacent brightness and/or hue.

Meaning, there is no absolute color, the brain just learns what things have the same color, and how similar or dissimilar they are in hue to other objects. And for example “cold” colors are cold because we associate them with cold things, not because of some independent “qualia”.

I feel like there needs to be some sort of intermediate black screen between the questions, a visual "palette cleanser" if you will. I was actively noticing the saturation of the color decline as I stared at the screen.

I think there's an anchoring effect in play here. If you select blue -> blue -> green -> blue -> green -> blue -> green…, you land at the population median. (The point being that, once you get to a somewhat ambiguous point (after two blue selections), you can say "oh, well, compared to the last one this is {opposite color}!", and it seems most people do that.)

My boundary was hue 188, bluer than 98% of the population, for me turquoise is green and then it shows an overall chart which I have to agree with so no, I don't agree with your assessment. I often get into blue/green arguments with my children and that's when I started to suspect that it was personal opinion.

That’s the point of this. To find out where in that spectrum your vision lands, not to get a perfect score.

OP's point is that this isn't valid because neither of the answers are correct. If you're really trying to measure a spectrum then the answers should allow for fuzziness. That is, you have a range/confidence interval of where green ends and where blue starts and in between is neither/both.

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