The Colour Change Charm is a spell that causes the object to change colours.

1991
"Sunshine, daisies, butter mellow, turn this stupid, fat rat yellow."

- Ron Weasley

When Ron Weasley 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. Later in the school term, Hermione Granger also performed this charm during Harry's first Quidditch match on a banner that Scabbers ruined. In Lego Harry Potter Years 1-4, the incantation is "Multicorfors" (MUL-tee-cor-FORS) and changes the color of the victim's torso.

1996
During Harry Potter's Charms O.W.L. in 1996, he accidentally switched the incantations for this and the Growth Charm.

1997
Harry Potter used this charm when he came of age to change the robes of the Chudley Cannons posters in Ron's bedroom to bright blue.
