Sir,you need to remember that not every batch of coloring and weave would have been the same.The chemicals in the coloring would be different every time,so there really isn't an exact color you could go with.The weave would be slightly diffrerent too.The uniforms material/color wasn't going to look the same every time.Just go with what gives you the best example of uniforms for troops during Vicksburg.
