"Interesting color" indeed. My '62 Dispatcher was Peacock Blue. Faded after years of Florida sun torture, the only way I could see the "original color" was under the transmission tunnel behind an undercoated spot. With that color-patch in mind, I looked for like-colored picture examples. Even different "color chip" sites show color variations (on the same monitor).
I think the 'why' we can't find any true examples and see so many variations, is apparently the green tint in the "Peacock Blue" fades out so when people "color match", they end up with more of a blue without the original amount of green in it. My faded "Peacock Blue" looked almost like 1963's "Sierra Blue", all primed over now. I wonder if that pigment change was on purpose from the factory to hold up better? I too would love to see an example of a full paint job of a true "Willys Peacock Blue". Good Luck.
