Put a torch in the same box as the lanterns. A red lantern lights only from a burning one, and a stack on the roof with nothing to light it is a wasted moment. Every player knows the torch from the start, and it takes a single unit of fuel.
So the waste solves itself. Crafted alone, a red lantern leaves three units of low grade fuel over from its last batch, and the torch eats one of them. The lantern is a skin of the plain sky lantern: no blueprint of its own, no research, the same bill, with red picked at crafting if the skin is yours.
Once lit, the red lantern flies like every other colour. The choice is mood, not numbers.
