But that is wrong. This doesn't test colour perception or vision, it tests verbal classification of colour perception into a forced binary. Everyone could be perceiving the colour qualia 100% identically, but simply choosing different linguistic cutpoints, meaning you can't say this is about vision / perception at all (it may just be about language use).

I think the premise could be stated more clearly. It is a boolean choice. What do you think it is closer to.

Once I figured it, I tried it 2 more times ... and got different results :) but the new results were consistent.

Agreed, there is no clear premise. Of course that different people looking at the same object will use different colour words is a triviality that anyone over, say, 10 years old knows. If that's the premise of the site, it is boring. People are getting excited because they think this implies something about differences in vision or perception... but it doesn't, that requires much more cleverness to test.
