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 Holding my phone at arms length all of the dots are purple.

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

@Danpiker i don't see it

@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.

@PhilSalkie @Danpiker Huh. Does this means that we shouldn't be writing small text or rendering small details in blue?

Amazing, I feel like my smartphone can track my eyes

@Danpiker It turns... a slightly darker blue, I think?

@Danpiker I definitely see it. Very cool!

Yes. Whichever dot I focus on turns purple.

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

@Danpiker - where to use?

Doesn't seem to 'work' for me. I have no colour blindness of which I'm aware!

a #ProTip for those playing along at home – if you have “night shift” (iOS) or “eye comfort” (Android) on you’ll probably need to turn it off to see the effect, otherwise all the dots will just look purple

@Danpiker what's fascinating about this is that, as someone with deuteranomaly, _none_ of the dots is obviously purple for me, on any background. they all seem "blue, but if you told me they're actually purple, I would believe you", which is just really common for me.
that must mean that the amount of short-wavelength sensitivity loss in the fixated area is not enough to offset the confusion (and overall lower information content) of overlapping long/medium wavelength response?

@Danpiker TIL (from someone who said "this doesn't really work") - this doesn't work if your phone has a blue-light-blocking filter on it!

@Danpiker
Nothing happens for me
