RS is a LOT more intense. I have a fuchsia CDC birkin and a RS Karo. The two are very different when held up together IRL. Fuchsia seems to have more blue or purple in it, maybe? RS feels like there's more red in the pink.
fushia has blue purple in it whlie rose shocking has more "yellow"in it ! both on chevre that is (chevre coromandel and chevre mysore respectively)
plus the stitching on fushia is darker then on rose shocking i say your bag is fuschia. as it is cromandel and has the darker stitching
