Rarefish's picture to me is turquoise. I think a lot of guys are color blind to the degree of seeing turquoise as blue or red as orange. Different cameras put their own twist on color too. I have seen pictures in the past of engines from guys claiming to have blue engines from the factory and they are turquoise in my eyes. I was printer for 23 years and was tested for color accuracy and always scored in the 98%+ percentile. All three 69 Swingers and the one GTS I have owned all have/had turquoise engines.
