I'm curious if the coloring for the outfit looks as expected when you are in a conversation. We are looking into this issue and any information can help us track down what is occurring. The details already provided have already given us some excellent leads and we hope to get this all sorted out quickly.
I'm having that very problem as well, but it's only one piece of my outfit, just the torso. The rest are the normal colors. In cutscenes, in the preview window, it's all darker, and when I'm out running around it's light. Kind of weird running around as a pink Sith. I'm not sure if other people see me as pink though.
