The thing is, they say they do this to make it clearer that you can conduct cross-wiki searches. There are ways to do this without breaking the wiki's color scheme and robbing it of its individuality. I even sent them a picture of an amended nav bar with changes that would still make this perfectly clear while allowing it to be recolored.
