In calf, there is Bordeaux and oxblood. In shell, there is bordeaux. That last color is basically the #8, although not quite as dark or massively polished as Alden does it. It's between the two calf colors, but a bit closer to the bordeaux.
My guess is that if you knew how to do it and wanted to, you could polish it to be more like the Alden oxblood/eggplant/dark purple color.
