I have two female friends (one a tremendously strong climber) who have pink bikes.. and I mean EVERYTHING is pink. Great for them!

Personally, I hate pink. I would never buy anything pink. I prefer colors that kill and intimidate. The main difference is, my friends had the option to buy pink. Or powder blue. Or other pastels. The colors I liked were not as readily available for me, except when I went up the WSD carbon fiber food-chain or looked at men's bikes.

My LBS dealer told me that the higher quality of bikes for women, the less "pastel-y" they become. In fact, the women's team he sponsors unanimously asked that none of their bikes/kit had any pink in them.

My S-Works is stealth black and my Pinarello is black-red-white. To me, those are women's colors!
