This "test" makes no sense. Cyan, and especially turquoise are neither blue nor green, they are a mix (similar to orange between red / yellow).

I had actually a very hard time to answer the questions, needed to overlay most of the color with some mostly white / light gray window and only squint at the color around it to decide. In the end my result was 176, which is almost the exact turning point for most people (and that even while my monitor is set to be more cold than default; but like said I had whatever my monitor shows as "white" to compare; even that "white" is likely technically slightly blue-ish).

Color perception is anyway much more influenced by contrasts then anything else. (Likely similar to acoustic tones, which are very hard to name / locate absolutely than when comparing to some reference tone.)

Besides the things mentioned in the about popup, blue is AFAIK the color we have the most receptors for. So it's imho quite "natural" that most people perceive cyan—which is technically the exact middle—as blue-ish, and of course the color left to it, turquoise, is green-ish (and as it seems, for most people, the mentioned turning point).
