The line "After a hurricane comes a rainbow" in Katy Perry's song "Firework" utilizes imagery to vividly convey a message of hope and resilience. It suggests that even in times of darkness and turmoil (symbolized by a hurricane), there is always a chance for beauty and happiness (symbolized by a rainbow) to emerge afterwards.
