Firework Star

Firework stars are items used to determine the color, effect and shape of firework rockets.

Shape effects
A firework can only have one shape effect for each firework star used in the recipe.

Additional effects
In addition to the shape effects, you may add either or both of these additional effects.

Crafting ingredient
Multiple firework stars can be used when crafting a firework rocket, in which case each one will go off simultaneously when the rocket detonates.

Trivia

 * Going by descriptions, there are 29 quintillion (2.9*10^19) unique firework stars (plus 1 if you count the blank one in creative mode) and 19 quadragintillion (1.9*10^136) unique firework rockets (plus 3 if you count ones made with blank stars), but going by their visual effects, there are only 2.1 trillion (2.1*10^12) distinct firework stars and 39 sesvigintillion (3.9*10^82) distinct firework rockets.
