Yellow Flower

Yellow Flower is the sixth extended play (EP) by South Korean girl group Mamamoo. It was released by RBW on March 7, 2018 and distributed by LOEN Entertainment. The EP contains seven total songs, including the singles "Paint Me" and "Starry Night". The EP is the first album under the Four Seasons, Four Colors project.

Background and release
Following the release of "Paint Me" as a digital single in January 2018, Mamamoo announced their sixth mini-album Yellow Flower on February 20, with the release of the first teaser image. The group posted more teaser photos on February 26, the official track listing on February 27, daily teaser trailers featuring each member from February 28 to March 3, a group teaser trailer on March 4, and a "highlight medley" of the EP's seven tracks on March 5. The first album in a series of albums titled Four Seasons, Four Colors, Yellow Flower focuses on member Hwasa, represented by the color yellow and spring season, and features her new solo track "Be Calm." The album symbolizes the beginning of a relationship, like how spring starts the year and is associated with innocent love.

The cover art has flowers on it to reference Hwasa, since "화" (hwa) is the Hangul form of the Hanja word "花" (eumhun 꽃 화 kkot hwa), which means "flower".

Yellow Flower was released to physical and digital retailers on March 7, 2018.

Singles
"Paint Me" (Korean: 칠해줘, RR: chil-hae jwo) was released as a digital single on January 4, 2018. The tentative and minimalist power ballad peaked at number 36 on the Gaon Digital Chart and 43 on the Billboard Korea K-Pop Hot 100.

It also entered the charts in the United States, peaking at number 23 on the Billboard World Digital Songs Sales chart. The music video for the single, released in conjunction with the single itself, was posted to both Mamamoo's official and the 1theK distribution YouTube channels. As of December 2022, the music video has 10.7 million views when the totals from both channels are combined.
