I can only ever equate the colour with commercials such as the one tonner as I remember it being the predominant colour I saw them around in. Plenty of utes and not all that many vans. I remember a (HX or Z - leaning towards Z as I think it may have been an SL colour combo) sedan two tone colour combo that looked like the darker chamois colour (had the green tinge to it) below a green roof. One of the detailers at Packards had a very neat example in the late 80's.

Oh the heights of chique were well and truly met in the 70's!
