Is zero more positive or negative? You should be able to answer that.

  More positive. -0 is more negative.
  • yarg 2y ago
    It's neutral (-1 * 0 ≡ +1 * 0); don't confuse it for an infinitesimal (which can be positive or negative).

      Nah, zero definitely feels a bit more positive to me.

      I think they were referring to -0 in floating point, which does exist as a separate value from +0 https://en.m.wikipedia.org/wiki/Signed_zero https://en.m.wikipedia.org/wiki/Signed_zero

  But teal isn't a single point, it's a range. You can have teals that are more blue or more green than each other; they can't all be zero. Whichever one you choose to be the true transition point between blue and green, there will be teals that are more blue or green than that one.
  • yarg 2y ago
    Sure, but there's also a subrange at the (subjective) centre of that range that will not be perceived as either more blue or more green. And the teal that I referenced in my earlier comment was (for me) such a colour.
    • nayroclade 2y ago
      Saying it’s a subrange implies you can perceive differences in tone within it. In which case, reframe the question as “is this shade of teal closer to the blue or green end of the subrange” if you like.
      • yarg 2y ago
        No it absolutely doesn't. It's a well know fact that people are unable to distinguish colours that are too close together. You could even have a smooth gradient from colour 'a' through colour 'b' to colour 'c', where it's possible to distinguish 'a' from 'c' but not to distinguish 'b' from either 'a' or 'c'.

        That's not how it works. Maybe if I'm given two colors inside that range, I can say which is bluer and which is greener. Given just one color, I simply cannot say that it's green or blue, or even if it's more green than blue or vice versa. I stopped at the 3rd or 4th come because I couldn't give a honest answer. That makes the test useless. I can't complete it with correct answers, and if I give incorrect answers, the conclusion is useless.

      I think the main point of this test was to determine the position of teal in your case, as your definition of teal is the midpoint(-ish range) between blue and green. (For me it's more blue though.)
      • yarg 2y ago
        Then call it something else. But the point stands that there's a point at and around which the colours are neither blue nor green.
        • lifthrasiir 2y ago
          I mean, a good test would be able to detect that neither-blue-nor-green range and approximate midpoint as well, and it should be fair to say the midpoint is indeed the threshold between blue and green. (I don't think the current version of test can do this, though.)

  True zero is very rare. So you are saying that teal just happens to be the true zero?
  • yarg 2y ago
    No, I'm saying that the sliver of a chasm between the colour in isolate, and what I subconsciously imagine the midpoint to be, is so damned thin that were I to look at the colours side by side, I could not distinguish one from t'other. And (even if I could) a bluish teal would no more be a blue than a reddish orange a red.
