Is there a color version?

Once in a while a black & white film originally may get a color version later on DVD or Bluray, as in the film was done on color stock but finalized in black & white for the theatrical release. Was this actually shot on black & white film? I think this movie would look more amazing if you could really see the Big Blue ocean throughout. Even a mediocre film like Into The Blue (2005) was a visual treat with its bright blue oceans and white sand beaches. Jessica Alba's body didnt hurt either ;)
But yeah, Im just watching this film for the first time, having seen most of Besson's other films, and I had no idea it was black & white until I started it. It was a tiny bit disappointing when I expected amazing blue ocean scenes throughout.
