I only had one of my items color changed to gold and that was the Photonic Tribble box when it is packed up and the gold is really just like an orange yellow and looks really bad compared to the other item borders.
None of the rarities changed on my Fed character (except a boxed photonic tribble), but they did on my Klink. (Ones I saw were my Radan Tribble and my Tribble of Borg... they were gold on my Klink and Purple on my Fed.)
Didn't have much change for me either besides my boxed photonic tribbles and I saw as well that a hargh'peng torpedo in my inventory was now very rare purple whilst hargh'pengs in my bank were still blue, same mark as well.
Man is a gaming animal. He must always be trying to get the better in something or other.
