>> These sorts of tests also need to be done in controlled background lighting. Whether people are doing this in a dark room, in a sunny kitchen, or under green led lighting would be a greater factor than anything being tested.

Whether its a dark room or sunny kitchen, i'm not sure whether Turquoise is ever going to be blue or green. The entire question seems more like wordplay.

I don't think that's necessary for an informal test. Human color perception is extremely good at compensating for that and modern screens are relatively uniform and uniform besides. Cultural differences like the person downthread saying they consider anything with the slightest hint of green to be "green" seem far more impactful.
