Sets the time in for how long until firework explodes, set to 0 for instant explosion.
/summon firework_rocket ~ ~1 ~ {LifeTime:0,FireworksItem:{id:firework_rocket,count:1,components:{fireworks:{explosions:[{shape:small_ball,colors:[I;14602026]}]}}}} /summon firework_rocket ~ ~1 ~ {LifeTime:0,FireworksItem:{id:firework_rocket,Count:1,tag:{Fireworks:{Explosions:[{Colors:[I;14602026]}]}}}}
