a few days ago I thought its sad that there is no dark theme out there for Codoforum Version 4.6.+
Then I made a copy of the CF 2k18 theme and did some few changes (so far not that many) to get a slightly darker style. Even if you can already use it, its a work in progress and I will integrate more features and style changes in the near future.
For now you can make use of it by uploading the "cutebutevil" folder to:
your forum folder/sites/default/themes/
Then go to Admin Backend/UI Elemeents/Themes and activate the theme.
