The song mainly wants to express that each girl has her own unique color, and should not lose it or change it for a boy, or they will become a mosaic.
Mosaic MV shows Jolin's first attempt at hip-hop, Parris Goebel (The Great Artist's choreographer) did the choreography. This is also the first time that Jolin uses dance to express emotion. There's a "fierce dance solo" near the end of the MV, look forward to it! The director laughed because she looked like a ghost dancing. At that time Whoohoo started to bark non-stop, silence fell on the set, Jolin said it was terrifying! It was like Whoohoo could see something that they did not. Jolin said that Whoohoo does this sometimes, especially during Ghost Month.
MVs for the fast songs in MUSE are colorful whereas MVs for the slow ones have a black and white theme, this idea comes from Jolin herself! That's why Jolin's hair are back to black in this MV and why all the clothes are white.
The MV will be revealed tomorrow on Jolin's YouTube channel at noon Taiwan time.
