This mod gives you some more options for Hancock's Red Frock Coat. It was inspired by my initial disagreement with how desaturated the original was, so I boosted the saturation a bit to make the colors pop. A couple recolors later and here we are!

Right now we have:

Enhanced Original
Orange/Yellow
Washed-Out
Revolutionary
Joker
Red/Black

Check out rustyzombie's Hancock recolors: They're all muted colors like my 'Washed-Out' one, except done by someone who actually knows what they're doing! Really nice!
