apart from not giving the "neither" option of turquoise, you cannot just line up asking without neutralising perception in between eg. with a non blue/green and then white before the next test. Color perception is >relative< not just across individuals, not sure how someone interested enough in blue perception does not understand this.

In Korean, we have an adjective "푸르다". It is somewhere between blue and green. You can say trees are that, oceans are that. It also means unripe.

Yeah, so to me, tortoise is definitely blue.

Edit: typo tortoise -> turquoise

Interesting!

I have UV filters on my glasses and things really changed when I took them on of off. I was much greener with the UV filtering glasses on. I guess my eyes are not picking up on things somehow.

Thanks to the TMS9918, I know cyan when I see it! Years of seeing cyan on a composite monitor where hue is tricky to adjust. My tolerance for the amount of green allowed in cyan is higher. And if it's cyan, it's blue. I see I classified quite a few greenish as cyan therefore blue.

> For you, the turquoise is green!

No, turquoise is turquoise. You gave me two options, and you act like I didn't know that word exists

I suggest replacing "is" with "is closer to", since shown color is obviously not blue nor green.

My blue is in fact what others see as red, and vice versa, but I wasn't able to verify it yet!

It just keeps showing me the same color over and over.

Warm blue vs cool blue is another interesting social question: https://www.ducktyped.org/p/a-colorful-controversy
