I wonder if the colours are arranged by age according to the rainbow?

That would make Jaune third oldest (still allows him to be called baby brother by an orange Saphron) and the yellow of the lot. Next would be green adventure girl, blue glasses girl, indigo twins, little purple overalls bringing up the rear.

It would explain why only Jaune and Saphron have left home - everyone under Jaune is too young (or just barely old enough, since he’s 18-19 so the next one is probably 17-18), while the eldest (red) stayed home to help wrangle the mob.
