My strap is leather, light brown, and the fittings are black. You might want to go to a saddle shop and see what they can do for you in the way of a 40-or-so-inch 1 1/4 inch strip of hide, if you're looking to replicate the thing. There are indentions down the edges where the leather was tooled, but otherwise the strip's outer edges are rough-cut. It's probably very easy to duplicate.
Cheers.
