South Korean girl group Mamamoo will release a new EP this month.

The Korea Herald confirmed the K-pop stars will return Nov. 29 with an autumn-themed album.

The new EP will be the third installment in Mamamoo's Four Seasons, Four Colors series. The group previously released the EP Yellow Flower in March and the EP Red Moon in July.

"By adding member Solar's signature color blue, the album is full of the autumn mood. Stay tuned for the release!" Mamamoo's agency, RBW Entertainment, said.

The Four Seasons, Four Colors project centers on Mamamoo's four members each representing a color and object. Solar is blue and the sun, Hwasa yellow and flowers, Moonbyul red and the moon and Wheein white and wind.

Mamamoo teased the new EP in a tweet Wednesday. The promo image shows Solar, Hwasa, Moonbyul and Wheein walking hand-in-hand down a city street.

"[#MAMAMOO] 2018.11.29," the post reads.

Mamamoo made its official debut as a group in June 2014. The K-pop stars are known for the singles "You're the Best," "Yes I Am," "Starry Night" and "Rainy Season."
