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 is, but im saying “is turquoise/cyan closer to being green or blue” in a given person’s perspective. For my perspective, turquoise is a shade of blue that leans toward green, but not a shade of green. The same as vermillion is a shade of orange, although it is red leaning.
Other people may perceive turquoise as being just a green as I think it is blue. That is really the point of the test. Not “do we see the same green or blue”, because the question isnt about what green or blue are at the extremes. Its about cyan/turquoise as you said
