The names of the fairies in "Sleeping Beauty" are Flora, Fauna, and Merryweather. They are easily identified by their dress colors: Flora wears a pink dress, Fauna wears green, and Merryweather wears blue. In addition, each of these fairies has her own personality.
Flora's name refers to the Roman goddess of the flowers, or to plant life in general. She is the unofficial leader of the three fairies. She behaves similarly to Fauna, which may reflect the fact that the animators originally wanted the fairies to have the same personality.
Fauna's name refers to the Roman goddess of animals, or animal life in general. She is the calmest of the three fairies and does not argue as much as the other two. She is similar to Flora.
Merryweather's name can be broken down into two words meaning good weather or good omens. She is physically frumpier and stockier than the other fairies, although all of them are somewhat grandmotherly. Merryweather is also feisty and combative and often has to be held back to stop her from attacking Maleficent. Merryweather takes action much more than the other two fairies. She also has a sarcastic sense of humor that reveals the truth of any matter.
