My dissertation was on colour theory, so like to think I know about colour. The turquoise they're showing is more aqua than turquoise anyway, and aqua is blue, as is turquoise. That said, some turquoise is green based, but not the ones they are showing.
As other posters have said, colour does not appear in isolation, so this will make the test more difficult. Also, screen settings, everyone's will be different. Mostly though, most see colour differently.
Long story short, the test is utter garbage 😂
Edited to add 'Your boundary is at hue 171, greener than 66% of the population. For you, turquoise is blue'
PS. Looking at the colour spectrum provided, none are fit my idea of turquoise anyway!
