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 OK, so now, looking at it on my phone, they're all purple! And the one I look at is only slightly darker purple. Wild stuff. 😅
