Prior to the album's release, the band released a cover of Suicide's "Shadazz" on a split single released by Blast First Petite as part of their tribute to Alan Vega in October 2008. On 17 March 2009, the eight-minute music video for "Sea Within a Sea", directed by former Jesus and Mary Chain bassist Douglas Hart, was posted on the band's website. The song was released as a digital download-only single, and full details of Primary Colours also surfaced. Following the album's release, the single "Who Can Say" was released on 7" vinyl.
In a preview article, music journalist Mike Diver commented that the album was "set to be one of the year's best" and that it was "wholly worth all the hype that's attracted to its unexpected brilliance."
