"L'amour est bleu" (English title: "Love Is Blue") is a song whose music was composed by André Popp, and whose lyrics were written by Pierre Cour, in 1967. Brian Blackburn later wrote English-language lyrics for it. First performed in French by Greek singer Vicky Leandros (appearing as Vicky) as the Luxembourgian entry in the Eurovision Song Contest 1967, it has since been recorded by many other musicians, most notably French orchestra leader Paul Mauriat, whose familiar instrumental version became the only number-one hit by a French artist to top the Billboard Hot 100 in America.
The song describes the pleasure and pain of love in terms of colours (blue and grey) and elements (water and wind). The English lyrics ("Blue, blue, my world is blue …") focus on colours only (blue, grey, red, green, and black), using them to describe elements of lost love. The English version by Vicky Leandros also appeared as "Colours of Love" in some locations including the UK.
《愛情是藍色的》是於1967年由法國人安德列·帕潑（Andre Popp）作詞，彼葉爾·考爾（Pierre Cour）作曲的。Brian Blackburn後來寫了英文歌詞。1967年希臘女歌手Vicky.Leandros首唱此歌參加當年的歐洲歌唱比賽。1968年，音樂家保羅·莫里哀（Paul Mauriat）及時將此曲改編成輕音樂，就是後來的Love Is Blue，並在他的大眾音樂會上演奏，這首歌曲頓時成了六十年代末世界各地最流行的愛情歌曲！
