I read an interview with Trampas Ferree, the PRS employee and namesake of the color, and he said the base stain is gray before the green is applied over it. So the gray that may be more obvious over time is actually the base showing more as (I’m assuming) the green fades over time. Mine hasn’t faded at all, but I’ve only had it for a short time. It never sees its case, being out and played regularly, so if it’s going to fade it won’t take as long as a cased one. Beautiful color, though!
