Katy Perry's done it again! After the magical land of sweets in California Gurls and reliving her adolescent years in Teenage Dream, Katy Perry goes for an inspirational motif in Firework. The video shot in Budapest, Hungary tackles insecurity and hopelessness as Katy urges them to 'let their colors burst'. It's a great promo that doesn't fail to put a smile on your face, and it's Katy's best one to date.



The human firework formation is brilliant.
