Charlie, the 6-cyl used in full-sized Chevrolet passenger cars through the 1962 model year was the old standby 235 Blue Flame 6, and was still painted Chevrolet Engine Blue through that year.  Beginning In 1963, full-sized Chevies got the new 230 cid 6 which was based on the engine developed for Chevy II, and those were painted Chevrolet engine orange.   Chevy light truck 6's through 1962 were painted dark grey, just like they'd been in the 50's (Modelmaster US Navy Engine Grey--used on the crankcases of USN radial aircraft engines).  After 1962, Chevy light truck engines also went to Chevrolet Engine Orange.
