Obviously the characters aren't supposed to embody the flavors in any way -- it's just a total coincidence that the white girl with the blonde hair is vanilla and the only black girl in the pantheon gets watermelon. Hell, chocolate would have been less offensive (just ask Life cereal up there).
Dove Offers to Scrub Away Your Unseemly Blackness

In 2011, Dove launched a skin product intended to moisten and revitalize aging skin (we're not sure how, so we're forced to assume it involved kidnapped orphans and youth-draining elixirs). They tried to be inclusive with their promotions, and prominently featured a white, Latina, and black woman in their ads, all showing off hauntingly youthful flesh.
Unfortunately, their arrangement left a little something to be desired.

Not even one Asian woman.
Due to silly layout problems, Dove not only implied that their product could wash away your ethnicity, but also that this was desirable. If you think we're reading too much into it, keep in mind that skin-lightening is a real thing, it's not exactly uncommon for us to be told that white = success, and it probably doesn't help that our brains tend to interpret images as progressing from left to right.
It legitimately looks like this Dove ad is saying that dark-skinned girls have terrible, damaged skin, and that this soap product can "fix" them -- finally turning their consumers into the skinny blonde women they've always dreamed of being.
The ultimate goal.
After the inevitable firestorm of controversy, Dove issued a statement clarifying that "all three models were intended to showcase the 'after' product benefit" and that they "do not condone any activity or imagery that intentionally insults any audience."
Don Rickles was presumably insulted by this statement, leaving Dove mired in a hellish Mobius strip of perpetual offensiveness.
