    This illusion was new to me. Does whichever dot you look at turn more purple?

    Pretty neat how clearly this lets you see the reduced sensitivity to blue light in the very centre of your vision.

      @Danpiker This is trippy as hell! I also feel like the border is more distinct when it's purple, but I can't really check because they all turn purple when I look at them! 🤯

        @Danpiker

        Yes. Whichever dot I focus on turns purple.

          @Danpiker Not at first, because I was wearing yellow-tinted sunglasses. When I took them off yes.

            @Danpiker Fascinating! If you force your focus slowly moving towards a circle you can even get a gradiant.

                  @Danpiker interestingly it works better for me on the smaller thumbnail than on the full version of the image

                      @Danpiker For me, the dot that I'm looking at doesn't change, but the remaining dots fade into the background.

                        Have a look at:

                        https://gamesx.com/misctech/visual.htm

                        Your eyes have much lower resolution in blue light than in red or green, the article demonstrates that increasing the size of the blue pixels by 9 times (3x3) makes an almost imperceptible change in the image. Link rot has taken the extra images and a diagram showing a proposed pixel layout of a big blue diamond surrounded by small red and green squares.

                                  It probably means not just that but we should be compressing the blue layer much more than the green or red when doing lossy compression algorithms.

                                        This illusion was new to me. Does whichever dot you look at turn more purple?

                                        Pretty neat how clearly this lets you see the reduced sensitivity to blue light in the very centre of your vision.

                                        @Danpiker It also creates a blue trail when I scroll the image up and down. Neat!
