"...he wished he had not mixed up the incantations for Colour Change and Growth Charms, so that the rat he was supposed to be turning orange swelled shockingly and was the size of a badger before Harry could rectify his mistake."
—Harry Potter mistakes the Growth Charm for this spell[src]

The Colour Change Charm (Colovaria) is a charm that causes an object or animal to change its colour; a witch or wizard can use it to change the colour of walls and banners, for instance.

Known uses

"Sunshine, daisies,
butter mellow,
turn this stupid,
fat rat yellow.
"
Ron Weasley[src]
Caster(s) Dates Notes
Harry Potter Pre. 1991 Used this charm to change the wig of his teacher at St. Grogory's Primary School a vivid blue colour.
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.[1]
31 July, 1997 Used this charm when he came of age to change the robes of the Chudley Cannons posters in Ron's bedroom to bright blue.[2]
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.[3] It could also be because Scabbers was an animagus, not an actual rat.
Albus Dumbledore June 1992 Used this charm non-verbally to change the banners in the Great Hall at the End-of-Term Feast from the green and silver of Slytherin House to the crimson and gold of Gryffindor.

Etymology
