As delivered, as Eiretrains points out, the CIE logo on the ends was not as normal (i.e. white lettering, orange surround). It was white, though, rather than cream but discoloured like anything white, I suppose. But - in that "as delivered" form, they were not the normal orange. They were a distinctly browner shade, nit the same as anything else on the railway. Thus, in order to be accurate an orange loco would have to have the normal orange surrounded logo, not an all white one.
