During the 1955-1959 Chevrolet Task-Force truck years, the panel body style remained very popular. To help sales continue to grow, a two tone paint scheme was offered. This option was used for the business customer that planned on having their logo applied to the panel.
A wide band on the sides and back was painted Bombay Ivory*. This two tone paint looked very attractive, as is, when leaving the factory but it also provided the correct background for most company logos. The baked on factory ivory paint would hold up better and did not require sanding and painting by a body shop. Only a sign painter was needed to add the company logo.
The above drawing is from a page in the 1959 Chevrolet salesman's data book.
The two-tone paint is Dawn Blue with Bombay Ivory inserts.
The photos are of a local 25,000 mile 1959 panel truck also in Dawn Blue. Note how the white comes to a point at the top and bottom of the side door window opening.
* The Bombay Ivory inset was not offered on panels painted white.
