Sun Valley ttk theme is a modern Tkinter/ttk theme inspired by the Windows 11 (Sun Valley/WinUI) visual style, distributed as the sv-ttk Python package. It lets developers restyle ttk widgets with light and dark modes in just a couple of lines of code.

Use cases

  • make my tkinter app look modern
  • apply a windows 11 style theme to tkinter widgets
  • add dark mode to a python gui application
  • theme ttk widgets with a fluent design look
  • switch tkinter between light and dark themes at runtime
  • style python desktop gui without changing widget code

When to choose

  • you are building a Tkinter/ttk desktop app and want a modern Windows 11-like appearance
  • you need easy light/dark theme switching in a Python GUI
  • you want a drop-in theme requiring minimal code changes

When to avoid

  • your app uses only classic Tkinter widgets instead of ttk widgets (only colorscheme applies)
  • you need theming for Qt, wxPython, or other non-Tkinter GUI toolkits
  • you require deep customization beyond the Sun Valley visual style
