Anticipating a lifetime of regret, Shakespeare's character Biron says in Love's Labour's Lost, Act V, Scene 1: "Henceforth my wooing mind shall be express'd / In russet yeas and honest kersey noes."
In Shakespeare's play, *Love's Labour's Lost*, Biron declares that he will henceforth express his love in straightforward terms using the colors russet (yes) and kersey (no).
