Oh weird, I assume this is just because the white is relatively red compared to the cyan, right? As in if you took any image and coloured it in the same way then it would also look red.
Yeah, there seems to be a lot more going on here than just marketing. If you mask the logo, the red still works. I believe it has to do with the combinations of white/black, white/cyan, black/cyan and the relative size of the blocks to produce a red hue through complimentary color persistence or whatever it's called.
I think it's also the amount of blue overlay. If you zoom way in, the cola can has much larger chunks of uninterrupted white, whereas the hand has a lot more blue interspersed.
