This makes no sense. It's like asking:

    "Alice is in Denver. Is Alice in (a) Canada or (b) Mexico?"

    - Your boundary between Canada and Mexico is at 40° latitude, more southern than 53% of the population.

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.

How much does display calibration factor into this? I'm fairly confident it must impact the results, but unsure how much error it would introduce.

I always wanted to have a color calibrator and a few years back i bought one.

all my displays were so well defined out of the box, it wasnot worth it at all. Like you would need to use this particular profile for proper real industry printers to even have any benefit of it if even because all my displays were well calibrated.

I would argue that this would only make sense for highly profesional graphics designer and i don't think this experiment requires this level of granularity.

>> Your boundary is at hue 173, greener than 57% of the population. For you, turquoise is blue.

very subtle changes in color after the first two. it also seems to be repeating blue -> green -> blue -> green, for me atleast.

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 had the same discussion with the color of a river in Albania with my wife. The test says my boundary is a bluer than 85% of the pop - sounds about right!

I find that fascinating as well! I hope tech will give us the answer in our lifetimes.

> Your boundary is at hue 172, greener than 63% of the population. For you, turquoise is blue. isn't turquoise exactly (50%) between the two?

The "exact 50%", or the boundary between green and blue, is nominally hue 180, which is cyan. A search for the RGB, CMYK and HSL for turquoise yielded a few hue values from 171 to 174 (depending who you trust, and allowing for a bit of drift due to colorspace conversions). In any case, 171, 172, 173, and 174 are all on the green side of cyan.
