Lost Colours is a psychtronica group based in Leeds, active since 2016. The act is described as a Leeds-based band from the UK.

The project begins as a two-piece acoustic and alternative band from County Kildare in Ireland, with Dónal O'Sullivan on guitar and vocals and Fran O'Connor on keyboard and vocals. It forms in late 2009 and plays its first set at The Sugarclub on Leeson Street in Dublin. The music combines acoustic guitar and piano with a lighter alternative sound and lyric content that is presented as reflective and thought-provoking.

In early 2010, the band records a debut seven-track EP titled Coffee, Songs + Cigarettes. It is issued first on CD, then later on iTunes. The group then continues to write and perform across North Kildare and Dublin, building a following in the Dublin and Kildare area and receiving radio play in Dublin. Drums are also mentioned as a possible addition to the lineup.
