Your help is always welcome, Andrés.
Regional usage causes problems in translations. I remember some of the Spanish used by a friend from Colombia who tried to teach some of us a little Spanish. I remember his word for brown was carmelito and for gray was isabelino (after the Carmelites with their brown robes, and after Queen Isabella, who was supposed to have had her underclothes sewed on, thus gray and dingy). Neither definition is found in the usual dictionary.
