Santa Fe's first set of diesel-electric passenger locomotives was placed in service on the Super Chief in 1936, and consisted of a pair of blunt-nosed units (EMC 1800 hp B-B) designated as Nos.
1 and 1A. The upper portion of the sides and ends of the units were painted gold, while the lower section was a dark olive green color; an olive stripe also ran along the sides and widened as it crossed the front of the locomotive.

Riveted to the sides of the units were metal plaques bearing a large "Indian Head" logo, which owed its origin to the 1926 Chief "drumhead" logo. "
Super Chief" was emblazoned on a plaque located on the front.
The rooftop was light slate gray, rimmed by a red pinstripe.
This unique combination of colors was called the Golden Olive paint scheme.
Before entering service, Sterling McDonald's General Motors Styling Department augmented the look with the addition of red and blue striping along both the sides and ends of the units in order to enhance their appearance.

In a little over a year, the EMC E1 (a new and improved streamlined locomotive) would be pulling the Super Chief and other passenger consists, resplendent in the now-famous Warbonnet paint scheme devised by Leland Knickerbocker of the GM Art and Color Section.
Its design is protected under a U.S. patent, granted on November 9, 1937.
It is reminiscent of a Native American ceremonial headdress.
The scheme consisted of a red "bonnet" which wrapped around the front of the unit and was bordered by a yellow stripe and black pinstripe.
The extent of the bonnet varied according to the locomotive model, and was largely determined by the shape and length of the carbody.
The remainder of the unit was either painted silver or was composed of stainless-steel panels.

All units wore a nose emblem consisting of an elongated yellow "Circle and Cross" emblem with integral "tabs" on the nose and the sides, outlined and accented with black pinstripes, with variances according to the locomotive model. "
SANTA FE" was displayed on the horizontal limb of the cross in black, Art Deco-style lettering.
This emblem has come to be known as the "cigar band" due to its uncanny resemblance to the same.
On all but the "Erie-built" units (which were essentially run as a demonstrator set), GE U28CG, GE U30CG, and FP45 units, a three-part yellow and black stripe ran up the nose behind the band.

A "Circle and Cross" motif (consisting of a yellow field, with red quadrants, outlined in black) was painted around the side windows on "as-delivered" E1 units.
Similar designs were added to E3s, E6s, the DL109/110 locomotive set, and ATSF 1A after it was rebuilt and repainted.
The sides of the units typically bore the words "SANTA FE" in black, 5"– or 9"–high extra extended Railroad Roman letters, as well as the "Indian Head" logo, with a few notable exceptions.

In later years, Santa Fe adapted the scheme to its gas-electric "doodlebug" units.
The standard for all of Santa Fe's passenger locomotives, the Warbonnet is considered by many to be the most recognized corporate logo in the railroad industry.
Early after Amtrak's inception in 1971, Santa Fe embarked on a program to paint over the red bonnet on its F units that were still engaged in hauling passenger consists with yellow (also called Yellowbonnets) or dark blue (nicknamed Bluebonnets), as it no longer wanted to project the image of a passenger carrier.
