There was an article in free newspaper called “Brooklyn!” (very creative, putting an exclamation mark into the name) about some school kids who participated in a robot building competition.
I bet those kids did not explain to the reporter what red boxing really is :) Uh, and the box that really brought some prominence to some kids was blue (One Steve made them, the other Steve sold them).
Boxes also come in all colors of the rainbow.
By the way, I really hate those robot competitions, like Robot Wars. They are nothing but glorified RC cars. If there was a competition of autonomos robots, that would be a bit more interesting, but probably also not watchable.
