Valentina 0.7.53 introduces a dark mode feature, which was a highly requested enhancement. The implementation involved customizing the user interface, incorporating built-in icon themes for Windows and macOS, and building a custom system to adapt the canvas-like scene to dark mode. Users can opt for explicit control over the dark or light themes, and the color schemes of the user interface and scenes can be customized by editing specific files. Valentina’s dark mode enhances the visual experience while maintaining the integrity of its functionality.
