If a uniform is worn repeatedly and washed, over and over, it will fade. This is why characters like Beverly, who wore the same blue uniform for the series run, seem to wear a much darker blue than, for example, Picard in "Tapestry". In that ep, his uniform was brighter, because it had never been worn before.
Nope. For one thing, fading from washing would not cause Beverly's uniform - which was not "the same uniform for the series run" or probably even for a single shooting week - to be darker
than a new costume.
Different dye lots and the use of different materials (wool for later male uniforms, Spandex for the first uniform designs for both sexes and for women throughout) accounted for most color variations.
