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...

It should probably alternate between blue/notblue... green/notgreen. I hit the same wall. Second question asked if blue/green when it was neither... and I really mean neither. I don't see cyan as a shade of blue or green, rather much like I don't see green as a shade of blue or yellow.

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.

No scientific line. But where does your mind put it if asked without being told which it is? This test is about where you perceive that line to be.

72 green though where it drew me on the gradient at the end I definitely would say the line is on green. and the swatch that is says I think would be blue was, well turquoise and not "blue".

my path was basically: ok def blue, ok cyan which would be "blue", greenish sea-foam? teal? ok now I wouldn't call these green Or blue . Then kinda bobbled the guess

crappy monitor aside, Feels like there's a combination of factors, some color fatigue from looking at a full screen saturated color and I think some "over thinking" the colors.

Also no way to account for the variation of LCD displays. The same "colour" can look different on two different panels

Wow. Did anyone else have some serious trouble with this?

The first color was obvious to me, as it was designed to be (it even tells you if you intentionally misclick). But at the very next color, the first "test color", I literally face palmed and said "oh my god" out loudly.

It was so, so hard for me to decide. I really just wanted to pick a non-existent "teal" option. Both "blue" or "green" felt wrong and equally right at the same time.

It just got harder from there. At the end, it told me that my threshold is "bluer than 80% of the population", but honestly, I don't think that's really true in my case. I was so ambivalent, my choices really felt random to me very quickly.

Should this be called "Is my monitor's blue your monitor's blue?"

I got a 98-percentile result and realised my Mac had Night Shift turned on.

I want this but for blue vs. purple.

I am bluer than 78%. Colors. How do they work.

I'm bluer than 98% apparently. For me, turquoise is green. I didn't realize that's not normal. If I'm off on a detail like that, then...uh oh.

blue than 90%, same verdict with turqouise, though what I call turquoise is bluer than what is shown

I have my doubts about the value of a two-alternative forced choice task for this. I was pretty much answering randomly both of the time because I wouldn't ncessarily have called either green or blue.

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!

...I get different numbers depending on which eye I use, but both are fairly center. I didn't expect blue-green to be affected though! My left eye can't see certain shades of red as well as my right eye. Bright sunlight makes it more noticeable, but my own skin looks weirdly (sickly) yellowish with one eye and normal with the other.

Whenever it's come up at home, my spouse simply insists "I don't need to know the difference between aqua, turquoise, and seafoam. They're all blue." At this point I just nod and agree, it's not worth the fight anymore. ;)
