Tecnicolor would have been the fourth album by the Brazilian band Os Mutantes. The album was intended to be their introduction in the English-speaking world and included English versions of songs from the albums Os Mutantes and A Divina Comédia ou Ando Meio Desligado, re-recordings in Portuguese and French and several new songs.
It was recorded in Paris in 1970, the tapes were lost until writer Carlos Calado, working on an Os Mutantes biography, uncovered them. Another version of the myth is that they were unsatisfied with many of the recording and abandoned the project to return to Brazil, explaining why three of the recordings were used later that year for their album Jardim Elétrico.
It was released in 2000 on Universal Records, with artwork by Sean Lennon, in order to capitalize on the growing interest in Os Mutantes following the re-release of their early albums in the late 1990s.
