I received a small frag of an unknown acro (was sold/traded to him as staghorn but we have our doubts). Long story short, when I had received the frag it was 99% browned out, as seen in the first photo. Fast forward 3 months and it has since turned full metallic green under my lights, which it is getting around 400 PAR. Meanwhile, his is currently purple with green polyps under around the same PAR. Is this possibly a result of it recovering from the “brown out” and still developing color? Third pic shows his colony that my frag came from.
