The black spots at the top are from using Reno and where my finger was rubbing, only a few showed up here but there are about a dozen like that. About the same as using Renomat above. After that I let them sit for awhile and dampened the other end of the T-shirt and wiped them down before brushing. You can see what came off at the bottom of the shirt. No color change because it was black shell but when brushing shell I prefer to brush shell, not cream. You could play around trying to match them and use Saphir Cordovan polish in Cordovan after stripping but in the long run I think it would better to just return them.
I try not to think of the color of the shoes as they come or on the website because a lot of color comes up on the original wipe-down with Saphir Renovateur (or any other conditioner/lotion). I've noticed this occurrence is even more pronounced on bourbon shoes with heavy burnishing.
As far as the color of the posted loafers, I would have recommended dying them a darker brown, along the lines of the darker shoe. Then, I realized they were shell and not calf. It would take a lot of work to get them close to each other, and I doubt he'd ever really manage to. If he wiped them down with some kind of conditioner/lotion, brushed them up, and still found them to be so distinct from one another, I'd recommend sending them back. Neither applying a quick coat of lotion nor brushing them down once should prevent the return of a pair of seconds. It could, however, help determine the true color before making a decision.
