Every pony's magic is subtly different. However, based on the precedent of Celestia and Cadence, there is no indication that simple mood changes and evern being depowered doesn't change their appearance much. It would take an extreme emotion to change their appearnace such as Twilight's 'fire rage' in Feeling Pinkie Keen.
