While many of the settings can be configured right from the device itself, others, such as changing the theme color and wallpaper, need to happen from the Microsoft Health app. To change the default theme color and wallpaper from your Microsoft Band, simply open the Microsoft Health app in your phone, tap Band and navigate to Personalize Band, then choose the theme color and wallpaper you want to display on your wearable fitness tracker.
