In my opinion, the colored spots, are often bruising, created by the tremendous energy of bullet impact. Could be what Shelby said also?
The pickle, works from the hair side of a cape, as well as the skin side.
If you take a REAL thick skin, rehydrate, and pickle it, and cut out a cross section, you will see 3 layers(before shaving-lets use an oryx for an example). White on the hair side, white on the skin side, and a yellowish area in the middle. The area in the middle, has not been fully re hydrated yet. Luckily for us, the pickle works from both sides of the skin, or we would all have a whole lot of trouble tanning thick skins, and keeping the hair intact.
