Nevermind Me, I May Be High

when it's made, the wax would mix making brown

But what if you took crayons of all of the rainbow colors, cut them really thin, then hot glued them together, making a rainbow crayon? How effective would it be?

it would look rainbow, but idk about the colors being even when you write, it might just not even write cuz the simulation would crash

Yeah, fair point.
