Ahhh, see, I've been collecting Dark Angels for a while, I tend to start dark and highlight up. But I prefer dark dark angels. So I guess it depends on what look you are going for. GW used to have some good articles on the store website about painting all facets of Dark Angels (white robes, black/green/bone white armour etc.) sadly all gone now. I have a copy on file, if you want them, PM me I'll send them to you.
