De Colores
No one knows for sure when the song first began to be sung in the Americas. The melody is thought to have been used in North and South America since the 16th century, having been brought over from Spain in the colonial era. However, the version of the lyrics sung today is thought to have been created by a group of Cursillo participants in Majorca, Spain, after one of the earliest Cursillo retreats in the 1940s.
