Unity Editor on Windows has never had a proper dark mode for its title bar, menu bar, and context menus, those parts of the window stay stubbornly white even when the rest of the interface is dark. This project fixes that. It's a small plugin that, once installed, turns those remaining light elements dark, giving you a fully immersive dark interface while you work in Unity. Installation is straightforward. You download a package file, double-click it to import it into your Unity project, restart the editor, and that's it. There's also a manual option where you place a DLL file directly into your project and configure a few settings in Unity's inspector. After the first launch, a configuration file is generated that lets you tweak the exact colors of the menu bar text, background, and highlight states to your liking. The primary audience is game developers and hobbyists using Unity on Windows who spend long hours in the editor and want a consistent dark interface to reduce eye strain. It works across a wide range of Unity versions, from 2019 through Unity 6, on both Windows 10 (1903+) and Windows 11. The author is transparent about the fact that you're loading a third-party plugin, so they also provide full build instructions if you'd rather compile it yourself from the source code. Technically, the project works by intercepting how Windows draws the standard window elements for the Unity editor window. It identifies the editor's main window and applies dark theming to the native Win32 components that Unity doesn't natively skin. The approach is based on a similar project built for a different audio application, stripped down and adapted for Unity with a custom color preset. The author notes no major known issues and invites bug reports. Removal is as simple as deleting the plugin file and restarting the editor.
