Which part of the masthead are you talking about, the edit counts? This kind of thing has to be done on each wiki individually in the respective wiki's CSS. Therefore, it can be done by admins only. I highly doubt admins would go through the effort of keeping a list of everyone's preferred color so I am guessing they just set the same color for everyone.
