Iago often hides in darkness to prevent people from knowing his identity. He stays out of sight in the wee hours of the morning as he and Roderigo goad Brabantio about Desdemona's elopement. He hides in shadows while Cassio and Roderigo confront each other, using the darkness as cover as he deals blows to both sides of the fight. Othello enters Desdemona's bedchamber by the light of a candle, and uses the light as a metaphor for her life, which he plans to snuff out as he would a candle.
Desdemona's and Othello's opposing skin colors are also illustrated through the text: Desdemona is called (rudely) a "white ewe" (Act 1, Scene 1) and "fair Desdemona" (Act 4, Scene 2), while Othello is referred to as a "black ram" (Act 1, Scene 1) and "black Othello" (Act 2, Scene 3). In addition, the contrast of Othello's dark skin and Iago's light skin brings situational irony to their portrayals in the play. Despite conventional associations of dark with evil and light with good, Iago, the light-skinned one—not the Moor Othello—plays the devil, which undercuts racial stereotyping of the day.
Iago (as the devil figure in the play) frequently uses beast and demon imagery to extend the negative associations with blackness he uses to manipulate the racial tensions in the play. In the very beginning of the play, he suggests to Brabantio that Othello and Desdemona are making "the beast with two backs," and Othello is "an old black ram." These beast references are like a pestilence that is contagious, and careful readers can track the moments in which the contagion is passed to others. Cassio, after getting drunk at Iago's encouragement, declares he is "by and by a fool, and presently a beast." And when Iago plants the seed of suspicion in Othello's mind, Othello, too, begins to use animal and hell references. When Emilia finds out Iago has used her, she declares in the final scene that she will "play the swan."
