Pale blue tactical markings for armoured car regiments?

[Rob McCue]

While restoring the SAR Halftrack we had the same confusion, Orders staes markings were to be in white , but the photographic evidence did not support white.

I found the attached in the Regimental War diary, stating all markings were to be reduced in size, "painted white and covered in green."

I assume an overwash of green to dull the white numbers/symbols, and thats why they do not appear as white in the photos.
