Flag represented with a dark blue shade - Image by Jorge Candeias, 17 December 2003
The flag of Delmas, as consistently shown in Carga e Transportes (Cargo and Transportation), the Monday's supplement to the Portuguese newspaper P&uacaute;blico, has a darker blue field. That might mean that the shade is not all that well-defined, or at least that they don't mind using a darker blue if they find it convenient for marketing purposes.
Delmas probably don't mind using variations of the logotype. Some of the trucks and containers of the company are painted white with the blue loogtype, that is the house flag with inverted colours.
