Colours (stylized as CoLOURS) is the fifteenth studio album by Japanese recording artist Ayumi Hamasaki. It was released on July 2, 2014, in Japan by Avex Trax, worldwide by Avex Entertainment Inc., and on July 18 in Taiwan by Avex Taiwan. The songs on the album were entirely written by Hamasaki, while production was led by long-time collaborator Max Matsuura; it also included a variety of Western producers such as Armin van Buuren, members from RedOne Productions De Paris and Rush, Darkchild, and Fedde Le Grand, among others. This became Hamasaki's first studio album to have not been fully produced by Matsuura, and her first album to incorporate a large amount of English language. Musically, Colours is an electronic dance music album.
