Alternative metal band Sleep Token has partnered with specialist publisher Rock N' Roll Colouring to release the band's first official colouring book, available worldwide from 5 December 2025.

The square-format book features high-quality paper and detailed outlines for fans to add colour using pens, pencils, or paint, The Moshville Times reports.

The designs draw from the imagery of Sleep Token's chart-topping album Even in Arcadia, including artwork of frontman Vessel and specially created mandalas. The release follows a landmark year for the anonymous, masked band, which signed with RCA, achieved number-one chart positions in the UK and US, headlined Download Festival, and received two Grammy nominations.

Rock N' Roll Colouring, founded by rock and metal enthusiasts, combines music with the mindful benefits of colouring. Sleep Token joins the publisher's catalogue alongside artists such as Iron Maiden, Thin Lizzy, Judas Priest, and Megadeth.
