Nonsense. My phone screen uses red, green, and blue to make up each pixel. The white pixels have their red component all the way at full brightness. Therefore there is a lot of red in the picture.
You could also see this by opening up the image and looking at the red channel which would not be completely black.
I think there's something more going on here than just "marketing". Because if you look at the tiny thumbnail in the OP it's very clearly red, and you can even load that thumbnail into an image editor and zoom in to see slightly reddish pixels.
So something happens when scaling this image that actually results in a red hue, and I don't think my computers image scaling algorithms are also falling for "marketing". I would guess it's actually some kind of sub-pixel trick that makes it seem like there's colors there which aren't, and that's why the image scaling algorithms also reveal the same colors you see.
That's wild as fuck. If I actually concentrate on the "red" it becomes white and then only becomes red again if I look away for a moment.
Here is an 8 minute video that goes into more depth on how this works. https://www.youtube.com/watch?v=0FjjJha7HMI
This is one of those actually cool optical illusions
Weird but if I focus my mind so to say it appears white but then if I relax then again red
...I was gonna say it took until it was shrunk down to the thumbnail to see red, but nope, it actually has red in it in the thumbnail.
Guess this is specific to how often you see cans of coca-cola?
Here, I put the image through a ditherer (only available colours are black, cyan, white). I don't see any red at all now.
[edit}
Actually, that "red" is mostly just gray so I played myself here. Still, the luminosity must be closer to red before I detect it as red, white doesn't do it.
Except that there is. Alright, maybe not exactly, but...
The whites that you see as white (in the other white parts which don't seem red), are shifted like
#E0F9F8. Notice the reduced reds there.The whites you see as red are shifted like
#F9F9F7. This one, I'd probably call yellow, but you get the point, reduced blues. There's probably a better example pixel in there and I just haven't found it.The red pixels in the thumbnail, well, maybe JPEG downscaling? I can't say, because I don't know what downscaling algorithm is being used.
So the parts you see as white, are actually bluish white in a sea of blue (Cyan is just mixtures of blue and green in case of RGB) and the part you see as red, are reddish white, in a sea or blue.
Also, for those who don't see red, don't look straight at the image. Look at something near it, with the image in your peripheral vision and you'll get what others are saying. But I guess that happened while you were reading the title.
Pretty sure this is stolen from a Facebook account I follow but I can't remember the name at the moment and will edit it in if I find it
Edit: the account name is Japanese
2nd edit: found it

Here's another version
The poster in the image is the original source for the coke can op posted btw
I only see the red when its small, in the thumbnail its red, but when I open the image its very black and white.
The white has more red in it than green and blue, so that's probably the cause of the illusion.
And what color does white have?
Great lectures on this kind of thing:
Burn the witch!
Do I not see the color because I'm protan or what? Does that even make sense for optical illusions?
Permanently Deleted
I only see red if I take my contacts out and hold my phone really far away, but then its all one blurry mess.
Shes right.
