Before you queue white boomers, ask whether the night needs one. The boomer is the big shell, a single burst high over the map, paid for in gun powder. For a goodbye on the roof, as on the item page, one is plenty.
For a longer show the smaller fireworks stretch the same sulfur further. A White Volcano Firework takes half the powder and sprays from the ground, and a roman candle skips powder entirely, running on fuel and fragments. Mix a few of those in and keep the boomer for the end.
All three are crafted only by owners of the item, with no research. If white is missing from your menu, you do not own it, but a teammate who does can craft it for you.
