Edit: I have now found out that Caterpillar Changed the color from the Old Caterpillar Yellow, also known as Hi-Way Yellow, to New Cat Yellow on their machines in June 1979 and that could be the case with the engines too.
So if that's correct the engines would be Cat Hi-Way Yellow from January 1932 until June 1979, after June 1979 New Cat Yellow...except for the cases when the truck manufacturers had their own colors as listed below.
The old Cat Hi-Way Yellow were a brighter shade yellow than the New Cat Yellow wich is more to the mustard shade.

The Maxidyne engine colour was gold, the Maxiydyne truck could easily be identified by the gold dog on the bonnet.
The Thermodyne, Econodyne motors were all painted GREY, these had a chrome dog fitted.
If any other brand of motor was fitted, Cummins,Cat, GM-Detroit, then it would have a chrome dog fitted as well.
Exceptions, some truck manufacturer's use their own colors instead of the engine builders color
AutoCar - White through 1968-69 then manufacturer color
Ford - Black until 1965, Ford Blue until 1982, Ford Corporate Grey
Diamond Reo - Red
International - Red
"International paid Cummins, Detroit and Cat about $25 per engine to have them all painted IH 2150 Red for many years. The practice ended in the '70's, as I remember, and we (International, my employer) pocketed the 25 bucks. Concerning the blue International V-800 in the Paystar, marketing decided that International's new big bore engines should be blue to distinguish them from the competition"
Peterbilt - White through 1984 then engine manufacturer color (there are exceptions as white engines can be found in trucks after 1984 and manufactures colors in trucks before 1984)
Caterpillar was the last engine manufacturer to stop painting them white.
