Info needed: correct colours for WWII Aust vehicles

[Big D]

Gina - a visit to the AWM is on my radar.

Tony - I think you are right about painting with the spade in place on that scout car. I have blown the photo up a bit and it certainly looks that way. So you reckon that is light earth on the scout car and not light stone? I must admit my uneducated eye can't tell the difference on these black and white photos. I had been leaning toward light stone for my paint pattern but light earth might be more appropriate.

I don't see the light earth in the paint sample plates listed. Am I right in thinking the light earth doesn't appear in those paint samples because it was added in January 1943? Is/was there then a set of paint samples which have all these new colours?
