engine color question

Ok i have a 69 dart swinger 340 does anyone know the right color for the engine i was told red so i painted it red but i really think its the Turquoise so if anyone can help on this one it would be great cause im going for a full restore and a wrong color engine would not be good. thanks.
My engine in my 69 Swinger 340 was originally light blue. I didn't like the color so I painted mine Ford blue. I always felt a little bad for doing that until I found out that Buddy Martin (of Sox & Martin) painted all of their engines Ford blue so it eased my feelings of guilt. LOL
