While neat, I don't get consistent scores if I retry it a few times. If it leads with a series of greens first, my score is more green oriented, and vice versa.

It is mentioned on the about page but I still feel like pointing out that your response to this test has as much to do with your perception of colors as how green or blue your screen is and what kind of ambient lighting there is. Especially considering how subtle the differences are in the final rounds of the test.

Still an interesting experiment, but I would be cautious about drawing conclusions about anything from it.

I was always fascinated by this kind of question as a kid. Like I would imagine that everyone had all the colors mixed up and we were each seeing something different.

It looks like this project got forked and updated further https://ismycolor.com/

My mind was blown once when I heard multiple people calling yellow Gatorade (lemon lime) green. I have no clue how anyone perceives it that way.

This only checks a single brightness level per hue. I bet that two people who agree for those levels might very well disagree at other levels, and vice versa.

The test's gradient does not have even luminence/saturation.

It needs to interpolate between blue and green in the CIELAB color space.

If you're not colorblind, yes. More or less.

Not much sense for the evolutionary machinery to keep the whole backend the same, but diverge in the perception part.

On the third step, this is turquoise and there is no button for that answer.

> Your boundary is at hue 181, bluer than 87% of the population. For you, turquoise is green.

Pretty sure I accidentally picked blue for a green once.
