I must be colourblind, most of those look the same on my phone.

Same. There were like three different colors at first and then the remainder looked mostly the same.

Also, I wonder how the results are affected by my screen and environment. I’m on an iPhone in a dark room, with brightness turned all the way down and I currently have TrueTone enabled and Night Shift enabled.

I was bluer than x percent of the median. Night Shift mode reduces blue light exposure. At daytime with Night Shift off, I would surely be seeing the boundary earlier, as there would be more blue light transmitted by my screen.

I may have to repeat the attempt multiple times on different screens and lighting conditions (both indoors annd outside) and see if the results vary wildly or not. I think they will.

>> Your boundary is at hue 177, bluer than 76% of the population. For you, turquoise is green.

Not really sure how to interpret this. Where is "normal" on the curve?

It seems to me there is a broad range of "normal", as in well within the standard spec sheet tolerances for humans. It is more about what is average or median.

The About section at the end said most people average around 175.

I forgot that my display is in night mode (reducing blue light intensity). And I ended up with "your boundary is bluer than 98% of the population."

If you have a spare moment today, look up "wine-dark sea". As far as we can tell, there was no such thing as a _concept_ of blue in Ancient Greece.

Some languages don’t make a distinction. And if a language doesn’t have a word for green or blue it won’t have a word for brown or orange either.

In Japanese, the "go" traffic light is referred to as "blue."

Showing the completion screen and giving the ability to use a slider to pick the center might be more useful.

This is also going to be very difficult because:

* HDR vs SDR mode

* Different monitors have different color replication ranges

* Monitor and OS color and brightness controls (brightness affects color perception)

* Interior lighting

* Monitor technology (LCD, OLED, etc)

Meaning even if a color was meant to be X, it just won't appear that way given the combinations above.

I did it twice. The first time, I was bluer than 57% the second time I was greener than 63%.

This is flawed. Turquoise is not blue or green. Also different displays will show different colors. And a lot of displays aren’t great at producing the hues in the green color space. Idk the test seems arbitrary, but I’m not color expert

I'm not sure what's going on, but in Chrome my median point is heavily on the blue side but in Safari it's on the Green side. Also, at least in Safari, reset leads to a series of perceptually unchanging turquois screens -- it seems a bug. Refreshing fixes it for the next run.

Noticing on my monitor that it's more blue if I tiptoe and look down, and it's obviously green when looking at below.

I think a better way to standardize this without too much variance in color would be make the user denote on the screen where they are actually looking perpendicular to the screen and judge from that area.
