The Color: Four stripes with melony orange alternating with dark brown and dark blue.
The Story: This poem from the 12th century tells the story of a fay-made horn that is enchanted to spill on a drinker who has been cuckolded (basically, whose wife has cheated on him). When Arthur drinks from the horn, he is soaked by the contents. Guenevere tells him a story of once giving a ring to a young man (hiding, of course, her affair with Lancelot!). Arthur is appeased by this story but even more so by the fact that the horn spills on every drinker but one. (Lots of affairs going on in Arthur's court apparently!)
