Categories need 4 colors, not 2.
Red: empty with no description brown?: (the color of a substub) just a description green?: contents but an empty/substub description blue: populated and described category.

The category system is for sure not perfect, but the red link is definitely better than making them all blue. Wikis that rely on category structures for navigation and sorting of items (eg... Commons) also rely on this red link 'alert'.
Something more flexible might be if there was a $wgAllCategoriesBlue or something that could be configured for each wiki, but a wholesale change would not be appropriate.
