Halos are rare, wearable accessories in Royale High. They have the possibility of being obtained from the fountain located in Divinia Park. When players obtain a halo from the fountain (not from trading), they will also receive a badge corresponding to that halo that does not appear on the player's profile.
Most halo items are not customizable. However, some of them can have colors or patterns applied from other items with the "Color All" feature. Some halos have the ability to be recolored as well.
The Glimmering Alien Halo is a special developer item that is currently the only halo that is not rewarded from the fountain but is also unobtainable by players.
