takes some detective work to find exactly what the original color could have been on any 50 year old truck ..... all I can say is there ain't any #234 on Tims chips 1inked above, or on any other chip sheets I've seen, and "G" isn't seen on any paint codes .... also I've never see Mariner listed for any 56-59, although there's a number of other named blues that could be a similar shade, like Empire blue
the
interiors were "marble gray" [med-light] and "charcoal" for the darker parts with the dash top flattened [charcoal], only originals I've seen with any other colors are Cameos
