Just a note, the only interior areas for Fort of Kings is the castle itself, so the inn/tavern is for show, not function.
As for the colors, Minerva/Nova built the area, and remember that we're limited in what placeables we have. I'm not exactly sure what Erilyn's colors or crests are but there's only so much we can do.
And as has been said, there's land exit. It's a walled city so try going outside the walls first.
