Titleist hasn't came out and told anyone yet that they are releasing a pink ProV1.  If you are referring to a previous discussion, they were just asking if they would make a pink one.  Sorry to bear you with the bad news, but don't count on one in the future either.

Pink stamped ProV?  Or pink ball stamped ProV?  With the almost annual 4 for 3 sale in early spring coming up, you may have an option for pink personalization.stampings.  You can also special order a minimum of a dozen, but I don't know if there is an upcharge.

Otherwise, someone posted a while back on how to dye golf balls.
