WhiteSur Icon Theme is a comprehensive SVG icon set for Linux desktop environments (GNOME, KDE, XFCE, Budgie, etc.) that emulates the macOS Big Sur visual style. It provides over 28,000 icons covering applications, devices, places, status indicators, mime types, and more, organized into multiple sizes (16, 22, 24, 32, scalable) and color variants (default, light, dark, and accent colors). The repository includes a well-structured Bash installer script (install.sh) that copies icons to the user's icon directory, creates symlinks for HiDPI scaling, and supports optional bold panel icons, alternative icons, and KDE Plasma logo replacement. The theme is actively maintained with a large community following. While not a software application in the traditional sense, it is a high-quality design asset pack with a robust installation mechanism.
