"Colours" is a song written and recorded by Scottish singer-songwriter Donovan. The "Colours" single was released in the United Kingdom on May 28, 1965 through Pye Records (Pye 7N 15866) and a few months later in the United States through Hickory Records (Hickory 45-1324). The "Colours" single was backed with "To Sing for You" (later included on What's Bin Did and What's Bin Hid) on the United Kingdom release and "Josie" (from What's Bin Did and What's Bin Hid) on the United States release. Donovan followed up the success of "Catch the Wind" with "Colours", which featured a similar folk style. The single matched the success of "Catch the Wind" in the United Kingdom, reaching #4 on the charts. In the United States, "Colours" reached #61 and marked a decline in popularity from "Catch the Wind". Donovan recorded the song a second time for release on his second album Fairytale.

When Epic Records was compiling Donovan's Greatest Hits, they were either unable or unwilling to secure the rights to the original recordings of "Catch the Wind" and "Colours". Donovan rerecorded both songs with a full backing band, and the rerecordings were included on the greatest hits album.

A live duet with Joan Baez from the 1965 Newport Folk Festival is included on the 1995 compilation Folk Music at Newport, Part 1.

The song was used in the film The Rules of Attraction.

"True Colors" was written by professional songwriters Billy Steinberg and Tom Kelly. It was both the title title track of and the first single released from Cyndi Lauper's second album.
