Favorite

Favorites can be set for a Sim in Create a Sim as part of their personality in The Sims 3. There are three types of favorites: food, music, and color. Sims will tend to choose their favorites when they can.

Favorites can only be changed with the "Change of Taste" lifetime reward from The Sims 3: World Adventures, but the favorite music can be changed with the testingcheatsenabled cheat.

Colors
In The Sims 3, Sims have a favorite color. The purpose of this is depending on the light colors, room colors, fireplace colors, and the color clothes they wear. When they are in a room with that specific color, they will have a better mood.

Food
The purpose of the favorite food is apparent: Sims who eat their favorite food will clap and laugh as they eat,and might get a moodlet, and get a mood boost. Sims will choose their favorite leftovers more if told to eat. With Late Night Vampires will prefer O-positive plasma, a type of blood in real life.

Music
Sims listening to their favorite genre of music will get a mood boost.

Due to a glitch in the game, it was possible to have a Sim's favorite music be "French" without The Sims 3: World Adventures. This was fixed in game update 1.8/2.3 on 12/15/09. A similar glitch was noticed with The Sims 3: Ambitions changing a Sim's favorite music to "Roots", and The Sims 3: Fast Lane Stuff changing a Sim's favorite music to "Rockabilly". Similarly, installing Sims 3: Pets changes a Sim's favorite music to "Country" if the Sim's favorite music was Custom Music.
