The livery when new was Nanking Blue, relieved by a broad white band extending the length and width of the windowed section along the sides of each car. The rounded nose of each motor-car bore the Pullman Car Co. Ltd. crest, and this was also carried on the white-painted band, between the last pair of windows on each vehicle. The roofs were painted light grey, the underframes aluminium, and the bogies black.

Yellow ends appeared on the sets from 1967. At least one of the LMR sets upon transfer to the WR had the drivers doors painted yellow also, and the yellow extended right to the bottom of the cab. On other vehicles the yellow stopped above the bottom leaving a blue band.

The enforcement of BR's corporate identity reached the Pullman sets in the early '70s. The official Pullman colours were then the reverse of inter-city stock, with vehicles painted grey with a blue band along the level of the windows. The cabs had yellow fronts - stopping below the bottom giving a grey stripe along the bottom. The BR insignia and "Pullman" was added in white transfers on the grey below the engine compartment grilles.

There is an undated photo in the Ian Allan Locospotters' Annual 1971 of an 8-car set in Sonning Cutting, with the front half in corporate grey/blue and the rear half in the original Nanking blue/white livery.  The same photo appears in an edition of Modern Railways (anyone know which one?). Thanks to Robert Carroll for this last item.
