[artist id="3274550"]Katy Perry's[/artist] next single, "Firework," is set to hit airwaves on October 26, and even though the song is about colorful outbursts, the single's stark artwork is mostly rendered in black and white. Perry, shot from her shoulders up, is rocking her signature bangs and wearing lots of eyeliner.

Perry also took to her Twitter account late Wednesday (October 6) to drop hints about her forthcoming tour. She

Perry tweeted about the "Fireworks" video shoot at the end of September, although at the time, she played coy about what song would be accompanying the clip. She simply noted that the end result would be "sparkling," which now seems fitting considering the song's title.

Perry didn't go into details about the clip's concept, but she did thank the people she worked with on Twitter. "Not gonna stop shooting till the sun comes up cause we are a LIGHT in a dark place!" She wrapped the shoot on September 30, saying, "I want to thank all the magical people that brought their sparks to this video the past few days ... your light reminded me of my purpose."

Perry has been open about her love for the song Teenage Dream's release. "People are coming back and almost adopting it as their own anthem, and it's hard, I think, to write an anthem that's not cheesy," she told MTV News. "And I hope that this could be something in that category. I hope this could be one of those things where it's like, 'Yeah, I want to put my fist up and feel proud and feel strong.'

"But I also don't want to be cheesy," she reiterated. "It's a fine line, and I think 'Firework' ... would be like the opus or my one song — if I had to pick a song to play — 'cause it has a great beat. But it also has a fantastic message."
