Dierks Bentley had the idea for the song early in the morning while sitting at the Nashville coffee shop Portland Brew before his songwriting session with Ross Copperman and Ashley Gorley. Bentley recalled to The Boot
"It was something I was thinking about for a long time, but I was cautious about wading into it, because I knew I wanted to write this song — the idea is about my wife. A lot of songs, you start with a good idea and it doesn't work out, and you move on to the next thing. Or you tweak the title and try to write it with somebody else. But with 'Black,' there's only one 'Black.' I can't write 'Blue;' that's already been written. I had this one shot with this song. I knew I had a great opportunity with these guys to get it."
Ashley Gorley added:
"Dierks is an exception to the rule. A lot of times, when you're working with an artist, maybe they're not as skilled as a writer; they're looking for people like me and Ross to give them that direction.
Dierks comes in - I have a voicemail at 6:30 AM, with him mumbling through some of "Black," which is a whole different thing. He knows what he's after, and we come alongside to help him get there. It's an ideal situation for me and Ross, with somebody like Dierks, who's kind of a writer first. And so, that helps, that scenario."
