Skin:Cologne Blue

Cologne Blue is one of the skins bundled with MediaWiki by default. It has existed since mw-hist>Special:MyLanguage/MediaWiki history|MediaWiki's inception between 2002 and 2003 as an alternative user option for the "monobook>Skin:Standard|Standard" skin.

Uses
It's been available as user option on Wikimedia wikis since its first version.

Installation
This skin is included in the download>Special:MyLanguage/Download|MediaWiki download tarball.

You only need to install it separately if you installed MediaWiki using a different method.

Bundled
In MediaWiki 1.23 and earlier, the Modern skin was maintained within the MediaWiki core repository. In MediaWiki 1.24, along with other default skin, it was separated from core to its own repository. It remains bundled with MediaWiki by default.
