The D- series is for stripping and the like. You need the painting style number for the color(s). Also the specification sheet may have additional information about decoration.
May we ask what locomotive are you working with? Original owner?
May we make you aware that
DeGolyer Library at Southern Methodist University has an extensive collection of the
specification sheets that it had microfilmed and then converted that to pdf format. Specification sheets list dimensions, material and much more information required to manufacture the locomotives.

Collection Materials
The DeGolyer is home to several Baldwin Locomotive Works collections: photographs, builders’ cards, drawings and manuscripts. Of particular interest to many railroad enthusiasts and historians is the digitized set of 56 bound volumes from the Baldwin Locomotive Works engine specifications, 1869-1938 collection.
