The one on the bottom right is badalassi russet, the middle one tobacco and the third from the right is seal, followed by natural covered by a black cloth to protect it from the light. The one on the front left is black.
The iPhone made the russet appear much lighter than it is, I took samples of the russet and the darker tobacco (which has just a hint of red tone in it), and this is more accurate.

Apparently, the russet tones are the hardest to get right so they get used up within a week. The seal will, over time, start to show through the underlying tones. Murray explained that the badalassi supplier is picky on who he supplies to. Aero does not shim the leather, it is supplied between 1.2-1.5mm. Aero uses only vegetable tanned leathers and try to minimise or not use chemically treated leathers.
