Two years ago i shared this website where you try and determine when a shade is either blue or green.
Posting it again because lemmy has grown quite a bit since then, maybe we have more people that havent tried it!
It ends with "For you turquoise is ___". Turquoise is turquoise. If I had to choose, I guess it's blue, and so my line is gonna be between turquoise and green, but it's actually turquoise. But I can see an argument for turquoise being green.
Ultimately, it seems like the actual question the test answers is "If you had to choose, do you consider turquoise to be blue or green?"
