Paint color question about the RoG 1/144 shuttle stack.

Hey Guys,

I'm placing an order for some paints and the RoG instructions are pretty poor as far as colors are concerned.

I'm looking for available equivalents to the following colors:

Wood brown (holzbraun)

grey blue (graublau) - there are like 5 different shades of grey blue (italian, french, navy, light, dark and RLM) - which shade is correct?

Panzergrau (tank grey)

And any idea what this "silky-matt" reference is supposed to be?  My guess would be satin, but most colors only come in gloss or flat.

Any help would be greatly appreciated.
