Colour by Numbers continued the commercial success of Culture Club's debut album, Kissing to Be Clever. The album includes several hit singles, with all tracks charting on the US Dance Club Songs chart.

The album peaked at number two on the US charts, trailing behind Michael Jackson's Thriller for six consecutive weeks.
The album was produced by Steve Levine at Red Bus Studios in London, where the band recorded their debut. They collaborated with session musicians, including keyboardist Phil Pickett and backing vocalist Helen Terry. The songwriting was influenced by pop history, with melodies inspired by artists like Gilbert O'Sullivan and Stevie Wonder.
Colour by Numbers is regarded by the band members as their best work. It has been remastered and re-released several times, including special editions featuring bonus tracks. In 2014, Boy George curated a live performance of the album with the BBC Philharmonic Orchestra, featuring various guest artists, highlighting the album's enduring impact.
