"Metamers" - images that look the same, but are different

Our illusions show the opposite: two images that are different but look the same -- those are called "metamers"; -- and two images that are identical but look different -- we call those "anti-metamers." Our main illusion mixes the two: it shows three images, two of which match with a third one mismatching. Viewers see one image as odd, but it's one of the two identical images they see as different, an illusion we call "false pop out."

    so that video, with the three images, has two "metamers",and, two "anti-metamers"? but two plus two = four, yet there are only three images?

    I don't get it. The one I pointed to was definitely the different one. Is this like the blue and gold dress?

      Which one did you point to when the video started?

      The one in the middle (at the start) was the one I pointed to at the start and it stayed that way,

      Apparently you perceive shape congruities better than the average person; most would view the far right one (at the start) as being different.
