But the point is, there is no line which separates white and black (or green and blue). 50% grey is neither black nor white, it's grey. Turquoise is neither green nor blue, it's turquoise.

I see it as having a blue component and a green component. If the mixture has more green than blue, then it's green.

The analogous version in black and white is "is this dark grey or light grey?" because that's the one asking you to guess which side of the 50/50 split the color is on.

Ok, but presumably you can make a test that goes from 50% gray to 100% black and you have to say "this is black" or "this is gray"

No scientific line. But where does your mind put it if asked without being told which it is? This test is about where you perceive that line to be.

but when does turquoise start and end and green starts and blue ends? or is there just another color there between them. And then what about that color?
