So far, what I have decided is primary color will be Maroon, including shoulder trim. The inside of the shoulder will be colored to designate Wing/Company. For other skull/Aquilla details, I am still deciding on Silver, Gold, or White. I will probably use the Dark Angels emblem but a different color, still up in the air but leaning towards either yellow/gold or green. The cloaks/cloth I am debating between dark green or black.

Chapter Name, or at least working name, is The Oathsworn. My Veteran/1st Company is designated as Bladewing. 

Mockup of potential Bladewing Veteran attached.
