Jealousy yellow

Green is more often associated with jealousy, but yellow is sometimes called upon to serve the same purpose (54). Phoebe, in The Yeomen of the Guard mentions “yellow, bilious jaundiced jealousy.” Moreover, since the gondoliers go on to say they will drown “Jealousy yellow” in the shimmering blue, might not the combination of yellow and blue produce green? (Rhetorical question.)
