The Colour Change Charm (Colovaria), also known as the Colour-Changing Charm, was a charm that changed the colour of the target.

	June 1996	During Harry Potter's Charms O.W.L. in 1996, he accidentally switched the incantations for this and the Growth Charm, so that instead of turning the rat orange it grew to the size of a badger before he could reverse his mistake.

Ron Weasley (failed)	1 September, 1991	When he was eleven years old, his brothers Fred and George convinced him to believe that a nonsense poem was this particular charm. The incantation was supposed to turn Ron's rat Scabbers yellow, but being a fake incantation, it caused no change whatsoever. It could also be because Scabbers was an Animagus, not an actual rat.

Etymology

The incantation for this charm comes from the Latin words color, colour in English, and variāre, which it means vary. So the incantation would mean something like "to to change/modify the colour".

• As Harry Potter confused the Growth Charm with this spell, it is probable that the two incantations are similar.
• It is possible that this spell was used on the colour changing Mahoutokoro uniform.
• It is possible that Albus Dumbledore used this charm non-verbally and wandlessly at the 1992 End-of-Term Feast to change the colour of the house banners from green and silver (Slytherin) to red and gold (Gryffindor), but it is possible that he used a different spell, such as a Switching Spell.
• In Harry Potter: Hogwarts Mystery, before the player starts to learn this charm in Transfiguration, McGonagall says that Tonks is exempted from this lesson for obvious reasons. While Tonks being a Metamorphmagus does have the ability to change her own physical appearance at will, this charm can work with other objects outside of one's body too, so it isn't really a good reason for Tonks to not learn this spell. Also, McGonagall associates this charm only with hair-colour changing. At the end of the lesson, the player will change a cat's colour instead of their own hair, but on the page where Transfiguration lessons are displayed, this charm is listed as "transforms the colour and style of the caster's hair" (not somebody or something else's hair). However, in a question asked by Rowan, the correct answer is that this charm is used to "change something's colour" (not just hair).
