Can you create a full article on this recipe if you can?

It'd require a full Koppepan bread recipe (divide dough by rainbow colors),

edible gold luster/edible gold spray (spray a bit onto the finished, cooled Koppepan buns),

golden food dye for the whipped cream,

And "edible gems" (Kohakuto? Jello Gems?)

My birthstone's the Aquamarine, shortly before Diamond.
