How to get Windows 10 light blue color on Windows 11?

You can’t get the exact Windows 10 default look in Windows 11, but you can make it very similar by going to Personalization → Colors and selecting a light blue accent color. Also set the mode to “Light” and apply the default blue wallpaper. If you want a closer match, you can use custom themes or tools, but for most users, the built-in settings are enough to recreate that clean Windows 10-style appearance.
