Space wolf fluff?

I've always wanted a full bleach-bone power armor space marine army, but I always pushed that fantasy out of my mind whenever I picked up a new army. Now that I'm converting over to the space wolves, I decided to postpone it no longer. Though I love the look of the marines, I was wondering if there was any space wolf fluff that encouraged going against the grain of the fenrisian gray of the legion? I know space wolves have "Great Companies" instead of chapters, but do the great companies ever NOT wear the chapter colors?

Just do it.

Fuck the system

Best response ever Chris. I lol'ed.

And yeah, the great company colors are chosen by the Old Wolf. Which is now you.

I need a chapter banner that says that now.

Well traditionally the chapter wears its colors. But the space wolf codex also says that all space wolves are very individualistic. This company can rebel against the "establishment" or you could have a fluffy reason why they wear that colored armor (Like the Dark angels Death wing)
