It is possible to craft sixteen different-colored Firework Stars in total. These do not have Metadata, and share the same Data Values as the normal Firework Star. It is not possible to craft the normal default Firework Star. Whenever a crafting recipe lists the normal Firework Star icon, any Star color can be substituted.
In addition, it is also possible to create different effects with Firework Stars, as well as change it's shape; players can add both effects Trail and Twinkle to their Firework, but only one shape can be added, Large Ball, Star-shaped, Burst and Creeper-Shaped. If no shape ingredient is entered, it defaults to a Small Ball-shape Firework.
