Is this because our brains have been programmed to see Coca Cola can as red? Or does it have something to do with the way the black and white boxes are organized? (I.e. if it were a sprite can, it would still be red)
I think it’s a bit of both. The light blue color used is so called “complement color”, meaning it’s exactly the opposite on the color wheel to the Coca Cola red.
Black and white pattern suggests to our brain to play with contrast.
And of course we all know Coca Cola from all the marketing.
Btw, After staring at it for a while I can kinda switch between red and white at will. Anyone else?
Interesting :) And yes, for me it also became easy to switch once I was aware of the truth of what I was looking at.
If you look directly at the can you can see it as white, but if you look elsewhere and the can is only in your peripheral vision it seems to always be interpreted as red.

No, that doesn’t seem to work for me, but after messing with zooming in, I can absolutely see it’s white if I’m all the way zoomed in on the black and white pixels in the can, and then as I slowly zoom out, there’s a specific moment when there’s enough of the surrounding blue that the can suddenly turns red.
The can remains black and white in my perception as long as I’m sufficiently zoomed in on it without the background. It’s a pretty neat effect.
Depends on the Lemmy app you use and your phone preferences for app opening certain links in different apps ( e.g. PayPal specific links may open in the PayPal app)
Ah this is a good point too, unfederated links could do it since the app wouldn’t know how to open it, I use sync and links usually work but occasionally will open in the browser.
It’s effectively your brain doing automatic white balance, it sees everything being tinted cyan so it just sorta subtracts cyan from the area, which results in white being reddish
you can do this physically (by tiring out the colour-sensing cells in your eyes) if you stare at a colour for about 30 seconds then quickly look at a white surface, you should see the inverse of the first colour.
The cyan is the one playing the trick. I can see the black and white nature without zooming when focusing on the logo or something. Sometimes it randomly changes from b/w to red

At the size it is on my phone screen it looks very red. Zooming in makes it look like the red switches to white.

Someone did a color swap and the can looks blue when the cyan pixels are instead yellow

How come this comment isn’t clickable in the app, and you have to open a browser to see it?

Thanks, I’m in voyager on Android. In the app settings, I can choose to open the link either “with default browser” or “in app”.
Even if it is set to “in app”, the app renders a browser window instead of just taking me to that comment in the thread.
Weird.
Try restarting your app. That can happen if an API request fails (or if you Lemmy instance isn’t federated with the target instance)

I have myopia so if I place the phone far from my face I can’t see that it is even a can… I still see a little bit of a red area there.
