 ### Windows
 
 ANSI color support in the terminal on Windows can be enabled by using e.g. [`go-colorable`](https://github.com/mattn/go-colorable).
 
 ```go
-logger := slog.New(tint.NewHandler(colorable.NewColorableStderr()))
+logger := slog.New(tint.NewHandler(colorable.NewColorableStderr(), nil))
