• This uptempo pop song about a teenage love finds Niall Horan assuring his girlfriend they'll be together for eternity.
  
  There'll never be another
  I promise that I'll love you for the rest of my life
  
  Horan imagines a wedding scenario where he's wearing a black suit and his girl is in a white dress.
  
  Yeah, I see us in black and white
  Crystal clear on a starlit night
• Horan explained to The Sun that he'd had the "black and white" title for a while and was wondering what he could do with it. He began thinking about a first love when a couple can't imagine being with anyone else. "That's it, me and you are getting married," he said. "I've seen it in the movies it looks exactly like this. So I just thought black and white would be like the black suit and white dress and it would become a bit of a wedding song."
• Horan wrote the song with:
  
  Frequent One Direction songwriter Julian Bunetta, who also produced the track.
  
  Sean Mendes' go-to collaborators Teddy Geiger and Scott Harris.
  
  Cuban-American songwriter Eskeerdo, who also collaborated on "Slow Hands."
• Horan played "Black And White" during the One World: Together At Home event that supported frontline healthcare workers. After singing the song, he gave a shoutout to essential workers for their time and sacrifice during the global coronavirus pandemic.
• The video shows Horan getting ready for a show before playing the song in front of a packed audience.
