User blog comment:Rupert Giles/Introducing Updated Global Navigation/@comment-452-20140924174247/@comment-856287-20140924211454

I don't decide whether or not Wikia will allow CSS changes to their new baby, but…

Pretty much works with pretty much any color, though you'd have to make some more styles to get it looking perfect with some colors. Hopefully the theme designer will work with the new global navigation like it did with the old, but even if it doesn't, it doesn't seem like CSS rules will be difficult to develop.

This stops it from scrolling with you, though I think you could only use this in your personal CSS.
