Welcome to Android Central!
Are you referring to the background wallpaper or battery saving mode grayscale?
For wallpaper, simply long press on the home screen and find the option to select "wallpaper". Go through the choices to change the wallpaper to the one desired.
If you are referring to the grayscale, then open system settings > power saving mode > power saving mode (on) > grayscale mode. You can disable that option by turning the power saving mode off.
Hopefully this helps. Let us know if you have any other questions.
