キミとワタシのオンガク  seiya-murai feat. ALT (Original song)

According to Motoco, the characters in キミとワタシのオンガク's video are named Moegi (もえぎ, green-haired girl), Nanoha (なのは, yellow-haired girl), Ruri (るり, blue-haired girl), and Sakura (さくら, pink-haired girl).
The girls' names are all derived from the names of traditional Japanese colors which relate to the colors of their hair, with "moegi" (萌黄) being a medium shade of green; "nanohanacha" (菜の花色) being a brownish yellow; "ruri-iro" (瑠璃色) being a deep blue; and "sakura-iro" (桜色) being a pale pink.
The four girls also have a bit of a resemblance to VOCALOID characters, from left to right, GUMI, Miku Hatsune (her Snow Miku 2016 appearance), Luka Megurine, and Rin Kagamine.
