I am beginning to wonder if it just wasn't an error in printing. If you notice, the background for the "darker" corn pop is dark red. Is it possible that he was supposed to be yellow, but the dark red bled into that corn pop making it brown instead?
First of all, combining variations of red and yellow
creates variations of the color orange...not brown
Secondly, if what you are suggesting, were the case,
it would be evident elsewhere, not limited to the face and hands...
his eyes and T-shirt(white) would be shades of red,
his cap, shirt and pants(blue shades) would be shades of purple...
not to mention, nothing would be clean, defined, within the lines
There is nothing to suggest nor support, such a theory...
his cap, shirt and pants are all different shades of blue,
his shoes are a darker shade of brown, then his face,
even the floor scrubber is different hues of orange
Someone intentionally chose a brown hue
for that one 'cornpop' and just the fact
someone had to sign off on the artwork
and approve it before it went onto the cereal boxes...
knowing all the crazy, race related controversies,
that could erupt from just a banana peel in a tree,
someone would have to be totally fucking brain dead
NOT to know, that was going to be an issue...
one way or another!
I wonder if it paid off
