I have a rouge pivoine evelyne and to me, it doesn't pass as a coral. It is an odd color. I don't view it as red red, it seems more "dusty" than that in some light it seems like it is more orangey red and other times more pinky red.
Rouge pivione reads red mostly. Hard to capture but gp is rp... reads red. Bad lighting but I sold the gp bc I wanted Coral. it's confusing bc they're pretty close but def Rj is Coral... birkin has more orange... totally Coral imo... and irl the difference is obvious to a color lover. Hth
Technically Pivoine is based on a coral/salmon peony flower but in leather to me it reads more red. I would say Jaipur is closer to the Pantone color you selected.
I think rj is closest to the color swatch you wanted. But it can be a bit neon/red-ish in different lighting. Imo a good reference of true coral is flamingo.
