German figure colors, any good referncess?

Hi there!

So far I have relied on my own photo referncess from books and web sites, counting on my own mixes. However somthing dosen't feel right, I've been wondering if there is a color chart (for differrent brands) that provides color data for the different whermacht uniform colors?
And please dont recomend on Valejo paints, I know how good they are but unfortunatly I can't afford them.

THANX!
