Not really. The Confederate supply system was abysmal. They often wore parts of captured Union uniforms, and uniforms weren't, well uniform, on either side. Some Union units had gray uniforms, and some Confederate units had blue ones. Both sides had many other colors and styles of uniforms as well. It was a hell of a mess, especially in the first couple of years.
that's one reason that First Manassas was "a mess".
