What colours for Maccabeans?

Hello,

I have a few armies in the post and one of them is a Maccabean army. I was wondering whether someone had suggestions how to paint their tuniques and shields?

I was thinking that it should be something closer to "back to the roots" rather than greek in influence, so probably light brown, beige and white.

For the shields:

-purple-red
-purple-blue
-yellow

Any educated guesses you would like to share?

thank you
Giles
