During the twentieth century, all but one of these was painted black, with white unit numbers on the sand domes and three sides of the tender. Cab sides were lettered "AT&SF" when operated in most parts of Texas, and "AT&SF" otherwise, also in white. The subsidiary Gulf, Colorado and Santa Fe often painted all or part of the smokebox (between the boiler and the headlight) white or silver. In 1940, the circle and cross emblem was applied to the tenders of a few passenger locomotives, but these were all later painted over. After World War II, "Santa Fe" appeared on tender sides of mainline road locomotives in white, above the unit number. Locomotives were delivered from Baldwin with white paint on the wheel rims, but the road did not repaint these "whitewalls" after shopping the locomotives. After World War II, side rods and valve gear were painted chrome yellow. For a short time, Pacific types 1369 and 1376 were semi-streamlined for "Valley Flyer" service, with a unique paint scheme in colors similar to those used on the new passenger diesels. More unique was the two-tone light blue over royal blue scheme of streamlined Hudson type 3460.
