This software adds new color themes to code on GitHub. Code blocks, pull request changes, and markdown snippets often look plain. This extension changes the colors to make code easier to read. You can pick your favorite theme from a list. The extension updates the GitHub interface instantly.
We built this for people who work in GitHub every day. Good colors reduce eye strain. You can choose from light or dark modes. Our collection covers many programming languages.

We add new themes with every update. Check the releases page for announcements.
If you do not see changes, check these items:

This extension only modifies how GitHub looks on your screen. It does not record your keystrokes. It does not send your data to outside servers. All color changes stay local to your computer. Your account security remains intact. We do not track your activity on GitHub or any other site.
We release updates to support new browser versions. When a new version comes out, download the fresh zip file from the link. Delete the old folder. Follow the installation steps again to install the new version. Your settings usually transfer, but you might need to re-select your theme.
We built this for the community. If you find a bug, report it on our GitHub page. Include your browser name and the version number of the extension. Describe what happens on the screen. We look at these requests to keep the tool working. You can also suggest new color palettes. We welcome input on creating high-contrast themes for better accessibility.
The project uses the WXT framework for smooth performance. This ensures the extension stays light. It will not slow down your browsing. GitHub pages will load at the usual speed. Enjoy your new coding workspace.
