Pink=Girl?

As a society, we associate the color pink with femininity. If you were to ask almost anyone you meet what they connect the color pink to, the answer invariably will be girls or women, or something of a female nature. Why do we connect the feminine and pink so strongly?
When a baby girl is born, pink is the signifying color, whether it be in caps, socks, blankets, or balloons. Boys on the other hand get "baby" blue as their hue. The color pink is linked closely to ideas such as flowers, Spring, certain fruits, and other things seen as father female in nature. When a man wears pink, it is generally seen as strange at first, usually "girly" by most. It is surely considered the least masculine color. It was not always this way. Many periods of history are marked with pink being the color of high fashion, gender aside. Sut how did this come about?
One theorists, Mary Rayme, postures the origins of this phenomenon to have begun during World War II. The Nazi's used color to distinguish their prisoners. We all know of the use of the yellow star of David to signify someone of the Jewish faith. What is lesser known is their use of a pink upside down triangle to signify homosexuals. This is one possibility as to how the effeminate qualities of the color pink came to be, though we still have no conclusive assertion.
