"Unbroken Bonds" set should match your guild emblem and colors.

The Unbroken Bonds set is the ship set you're awarded when you complete your 'Distinguished' Guild commendations, and getting all of them requires sailing in a guild of Distinction 10. Your reward for valiantly representing your guild is a ship set with the same colors as anyone else of a different guild who unlocks this set. The set is supposed to show that you've dedicated time to your guild, but the set itself does not actually represent your guild. I believe that the set should have it's current appearance as a default when put on a ship not sailing for a guild, but if this set is equipped on a guild ship, the colors and emblem on the sails and figurehead should change to match.
