Depends on ripeness, humidity, leaf position on the stalk, ambient temperature. If cut with the lower leaves just at maturity, in cooler conditions (where stalk-curing can take long, from weeks to months), I end up with a rather dull brown, generally.
At the moment it's very warm (far above 30 degrees Celsius the last week). The stalk-cured (in the dark) does not look very different from the sun-stalk-cured, just a bit more tanned, but also reddish (and some lower leaf seems to come out quite bright, after all).
I once hung overripe, primed Oriental leaf into a hot attic. It came out very bright, almost yellow. I also pile-cured Prilep and other Oriental leaf to yellow, then dried the leaves in the kitchen oven at flue-cure temperatures over a few hours. Very nice looking leaf, yellow-orange. They taste of both is interesting, but not my favourite. Especially not really incense-aromatic. It also tends to bite in the pipe.
I hear that once the leaf has colour-cured to yellow, drying should happen as rapid as possible. That has not really been my experience.
I'm getting the most aroma usually in leaf which I treated like cigar leaf, which took long to cure and dry (as long there's no mould developing), and that leaf is (colour-wise) as well often enough not the best looking. That's why stalk-curing seems to work for me better than priming for Orientals, but in a different climate (i.e. reliably "hot and humid" instead "hot and dry OR cold and wet") that may very well be different.
I've tried priming and sun-curing Oriental leaf before the way it's supposedly done in its native farming regions, with lots of leaves stringed tightly. Ended in rot.
As a downside, early harvest and long stalk-curing really compromise the sugar content. As a single variety for the pipe, Prilep still has plenty enough, for my taste. If the sun-cured above does not come out better or different, but also not worse than the ordinary stalk-cured, I've gained at least extra curing space.
