Matthew Giachelli got the call he anticipated on Thursday morning: The N.F.L. was moving the Rams’ playoff game to Arizona because of the wildfires raging in Los Angeles, and the league needed 200 gallons of paint pronto.

The game on Monday between the Rams and the Minnesota Vikings would now be held at State Farm Stadium outside Phoenix, and it had to look and feel as if it were being played in the Rams’ usual home, SoFi Stadium. That included painting the field with the team’s and league’s logos and colors. The hometown Cardinals, though, did not have some of the needed hues on hand, including the Rams’ blue and yellow.

Giachelli’s company, World Class Athletic Surfaces in tiny Leland, Miss., provides paint to most N.F.L. and top college teams. Within hours, he and his co-workers had loaded five-gallon buckets of nine custom paint colors, as well as stencils for the N.F.L. playoff logos, onto a truck that left Thursday afternoon on a 1,500-mile journey to Arizona.

“I definitely regret what’s going on in California, but I’m glad we could meet their needs,” said Giachelli, the vice president of production and distribution.

Getting the right paint was just one of hundreds of details that the league, the Rams, the Vikings, the host Arizona Cardinals and ASM Global, which operates State Farm Stadium, have juggled since the N.F.L. decided to move the wild-card round game.
