"Colours" is a song written and recorded by British 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" (previously 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 No. 4 on the charts. In the United States, "Colours" reached No.61 and marked a decline in the artist's popularity relative to "Catch the Wind". A different mix of the song (without harmonica) was released 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 re-recorded both songs in the studio with Big Jim Sullivan playing guitar, John Paul Jones on bass and keyboards and Clem Cattini on drums, produced by Mickie Most. The re-recordings were included on the greatest hits album.
