66 Formula S engine color

I have heard that the correct color is red. However my motor that was standard bore and appears to have never been apart before was more orange than red. Everything on it even the bell housing had a much more of a orange color than the red Mopar paint I used to repaint it. My 66 is an early model don't know if that matters.

Just thought I would throw that out there and see if anyone else had any thoughts on the engine color.
