When you create a sovereign and you are choosing clothes it says light or dark. But really this is missleading it should really say main or trim. To represent the color, becuase not all sovereigns have dark - trim colors or light - main colors.
But really instead of main and trim or dark or light, I recommend that you say primary and secondary. As most of the items I see do not use the trim color (I could be wrong here, I just don't notice it too often)
