I'm thinking about creating an Iron Warriors Army but unsure of color scheme. I have seen two different themes.
Does anyone know any fluff about them there is not alot in the newest Codex besides they are siege masters.Lastly, do they serve any one god or just "Chaos".

Thanks for any info

They serve chaos, but more chaos glory
I have personally only seen one major color scheme and that is in the codex
