If I bought or received a FF slot for free(back in 2015 I think) while being a silver account can I change the color of it's powers if I became a Gold member? Or can I only change the power colors on a FF slot obtained during a gold subscription? I've heard that silver Freeforms, even after subbing can't change their power color and would have to buy a new FF slot while subbed to make use of this feature. I couldn't find any answers on the forum yet and just want to confirm this before subbing.(or buying the premium pack if it comes out) Thanks.
