A seasonal promotion is an official offer sponsored by Grey Havens, to encourage customers to either buy more doubloons or else extend or renew subscription.
Each of these seasonal promotions has an associated trophy.
Some of these seasonal promotions are associated with an American holiday. Those which do not have such as associated holiday will instead have an associated special color. Any mystery boxes given out as rewards during such a promotional offer are of that color, as are the prizes contained within those boxes.
