The color blue has long been associated with sadness, while BTS member RM has used grey before to express a similar emotion. When his bandmate V set out to compose an intimate song about depression and wanting to feel happier, he used the two colors to convey how he was feeling.
V originally wrote "Blue & Grey" for a solo record. After he shared the melancholic song with his bandmates during the filming of the BTS reality show In The Soop, they decided to record it for their BE album.
The other BTS members all contributed to the acoustic song, during which they talk about depression, anxiety, self-doubt, artist burn out, and feeling lonely in the COVID pandemic world.
V produced the track with:
Big Hit Entertainment in-house producer Hiss Noise.
Jin Sanghyuk, a singer and friend of V whose artist name is Levi.
Los Angeles singer-songwriter Ji Soo Park, who records under the name of Nive.
