I was pointed to this thread:
Dutch East Indies Camo - Message Board - ezboard.com, which contains a good comment by P.C. Boer who wrote some books about the KNIL.
There is revealed that the colors Jong blad and Oud blad were not looking like (or even identical for aircraft painted by US factories) to QM42 and QM31
Reason enough top update the colorlist with this information.
