Illusion or not?!

Apparently, there is no red in this picture.

If you zoom in, the red disappears.

I read about this somewhere and the explanation was we see red for the can because that is the color we expect it to be.

I think there's a bit of red (actually, shades of red) in there that shows clearer the more you zoom out.

I disagree Boy to me GP's reply seems to make sense but I understand what you are saying.

print it out and look at it close under strong natural light - no red

the brain is doing it's usual thing of interpreting what the eyes send it, and in this instance getting it wrong; optical illusion

I opened the image in XDP, zoomed in and saw variations of hints of red (and other colors) in the white vertical bars. With the eyedropper, I also checked the black bars and they also have hints of red (and other colors). I imagine this was done on purpose to create the effect of a red can.
