The orange/brown difference was probably the result of a chemical reaction. In July 1907 the Banco de Durango sent the American Bank Note Company one of their $10 note, which had changed colour, with a different tint on the face, and said that there were other similar notes in circulation. The ABNC replied that this was a security measure. “If you will carefully examine one of these ten dollar notes, you will notice that the orange tint which is spread over all of the face, has a distinct pattern, although same is not very apparent. This orange tint is put on with the idea of security against counterfeiting by photography, and the note which you sent us proves its efficacy. Someone, evidently with the idea of obliterating this protective tint, so that they would be able to secure a clear photographic reproduction of the black work, has subjected the note to a bath of, say, sulpher, but has only succeeded in changing the color from orange to black, which brings out much more distinctly the [ ]oid pattern of the tint. The same chemical action has taken place with the orange back, changing the color to the brown as it now appears.”^{ABNC, folder 169, Banco de Durango (1906-1931)}.
