Nurgle Angels: Nurgle how to do?

So I have been thinking. How should I do my other squads? Like my Sanguiary Guard? How do I paint them? Normal Gold? Or just rusty? Here are a few options I wanna share with you guys.

Rusty like this?

Or a squad totally green like this but then with alot of Angel icons on them:

Or some plague stuff like this:

A squad of those is also a easy but expensive way:

I'm kinda lost so maybe some one can help me out?
I'm thinking:

• Sanguiary Guard: Rusty metal look.
• Vanguard Squad: A mix of forgeworld stuff
• Sanguiary Priest: Also a rusty look.
• Dante: Also a rusty look?
• One squad totally with nurgle gifts.

What you think?
