I'm sorry, I haven't seen any pink armor for players at all. They were really very restrictive with their color palette when designing their armor, particularly on the republic side
But for the record there is a guy right outside the Corellia (imperial) spaceport who, in certain lighting, looks to be wearing some kind of pink armor. I should probably double check to make sure he really stands there, or if he just walks up during dialogue..
