X removes Dim theme from web. How to get it back with an extension?

On X (Twitter), Dark mode previously had two dark color schemes: “Lights out” and “Dim,” but Dim has been removed.

In this article, we’ll clearly explain how Dim was removed from X and how to restore it.

Dim removed from X web client

Until now, X’s Dark mode offered two options: “Dim,” based on dark blue, and “Lights out,” based on black.

The Lights out theme has the issue that, due to its nature, it increases screen contrast, but the Dim theme can prevent the contrast from becoming too strong.

For this reason, the Dim theme was popular among some users, but it has been removed from the web version of X.

As of the time of writing, you can still continue to use the Dim theme in the X mobile app.

Nikita Bier, X’s Head of Product, posted about this, saying that while they currently don’t have the capacity to support more than two colors, they are considering making Lights out brighter.

In other words, the reason Dim was removed from X’s web client is a lack of internal development resources at X.

How to restore Dim

Control Panel for Twitter, a browser extension that makes X easier to use, implemented a feature in v4.22.0 to restore Dim.

As of the time of writing, Control Panel for Twitter v4.22.0 can only be used on Edge, but it is expected to become available for other browsers soon.

If you want to use Dim right away, you can paste the CSS introduced in this post into a browser extension called Stylus to make Dim available again.

When using Stylus, configure it with the following steps.

1. Install Stylus in your browser

   • Chrome / Edge version
   • Firefox version

2. Open X

3. Click the Stylus icon and create a style for [x.com]

   

4. The style editor will appear, so paste the CSS introduced in the post mentioned earlier and save it

Conclusion

Of X’s Dark mode themes, “Lights out” and “Dim,” Dim was removed due to a lack of development resources.

You can restore Dim by installing a browser extension such as Stylus and setting up a style, or by using Control Panel for Twitter.
