I find any knee-jerk to "girls only" marketing more than a bit wearing but this column in the Globe and Mail puts it far better than I could:

...It turns out that, as a woman, I require my beverages in a less threatening hue – like pink, which is the colour of a new “crisp rose beer” launching this fall in Britain. Animée is aimed at women, and also comes in white (clear filtered) and yellow (zesty lemon), because those are the colours of spring flowers, and ladies like flowers. It’s also less bloating, because ladies like skinny.

The author talks of pinkification but it may as well be stupification. Pretending one part of society needs special help understanding as basic an element of culture as beer is condescending. Suggesting that they need beer to be a certain colour for them to understand it is insulting and verges on paternalism. Me? Why is no one selling me a camo beer or maybe even on in a nice taran? It's not like I am buying Molson Coors non-pink beer. They need to colour a macro crap lager to attract my Pavlovian trade.
