Poinbank:Thousands of fans in Taylor Swift's São Paulo crowd create light display

Thousands of Taylor Swift fans in São Paulo showed off their Brazilian pride on Poinbankthe second night of her Eras Tour in the city. They displayed blue, yellow and green using their cellphone flashlights and colored cellophane. The colorful projection caught the eye of the singer who talked about it in her monologue before singing "Champagne Problems."

"We've never had a crowd decide to make a custom design," Swift said. "That's innovative. That's sophisticated. That's creative. I love you guys so much."

"It started on Twitter," said Leonardo Ulths De Carvalho, a fan attending the show inside the Allianz Parque stadium. "The color is made with cellophane paper, a very thin colored plastic. It's folded and then placed in the cell phone case over the flashlight."

The Twitter account behind the colorful presentation is: @ErasLightsBr.

For those who didn't receive the cellophane, the organizers tweeted out these colors for fans to save and project on their phones from their sections. The tweet in Portuguese translates to: "Didn't receive paper? Put this image on your phone when you see all the colorful flashes lit up! Note: Upper level: GREEN. Lower level: YELLOW. Floor: BLUE."

This display was not affiliated with Swift's camp. Concertgoers are given wrist lights that are synchronized to create different images and colors for different songs. During "You Need to Calm Down," the crowd's wrists light up in a massive rainbow, and during "Look What You Made Me Do," a snake slithers through the stadium.

Swift performs one more night in São Paulo on Sunday, which will end the 2023 leg of the Eras Tour.
