do you know if Luo (or any other recaster) makes dolls in a resin color similar to Iplehouse's "ebony"? I've seen Luo do fantasy

Sometimes. Luo/Steven will try and color match any photo but the darker cooler browns (like IH Ebony) are apparently very difficult to get consistant. There are a few dark brown recasts out there, but there are also a number of folks disappointed that their doll wasn’t dark enough (or was too reddish of a brown.)
