Symphonata Types

Symphonata Types (シンフォナタタイプ) are secondary-types claimed by the idols working under Symphonata Productions. There are currently four available of these idol types and two hidden types that can be accessed later by future idols. Each of the idol types are named after color types, have their representing color and representing asteroids. When idols are classified into this type, it has no basis of personality, background or interest, however, there are occurring stereotypes that the idols display of certain types (like Bright-type idols are usually energetic and expressive, whereas Cool-type idols have confident and mature personalities).

Overview
Once an idol signs the contract with Symphonata Productions, they are classified into an idol type in order to find brand, song, stage and work matches more easily. Charlotte Vert is usually the one who assigns the idols to their type but an idol can classify themselves into their own preferred type, as long as it has Charlotte's approval.

The formation and members of StellariS became the basis of the attributes of the first four types, acting as their leaders (Inori with the Calm idols, Carl with the Cool idols, Madoka with the Bright idols and Kokoro with the Pure idols).

Later (in the Mid-2018 updated), fashion designer Usagi Hishikawa updated the Symphonata brand system and that the idol types would affect the brands the user will be using it. There is also an ongoing theory by Usagi and Galileo that there are two more idol types registered by Charlotte that hasn't been seen or even used yet.
