It's especially tough when there are no lyrics!
Here's one of my favorites (by the way, it's called "Love Is Blue" by Paul Mauriat):
@jmyrlefuller @SanguineThat one actually has lyrics beyond MAD...

And in English...
https://www.youtube.com/watch?v=Kqa9eVL67HQ"Love Is Blue"Blue, blue, my world is blue
Blue is my world since I'm without you
Gray, gray, my life is gray
Cold is my heart since you went away
Red, red, my eyes are red
Crying for you alone in my bed
Green, green, my jealous heart
I doubted you and now we're apart
When we met how the bright sun shone
Then love died, now the rainbow is gone
Black, black, the nights I've known
Longing for you so lost and alone
Gone, gone, the love we knew
Blue is my world now I'm without you.
