Lighting is important as it extends Shakespeare’s thematic concerns with the lightness and darkness of character and skin.
Play begins in darkness. Entirety of Act one is in darkness. Critic: Norman Sanders: “The darkness helps to reveal Iago’s character because it is set in the night and it highlights the dark and devilish nature of his character.” The darkness feeds Iago’s malicious nature.
Textual evidence: Iago: “Hell and night/ Must bring this monstrous birth to the world’s light.” We see Iago’s obsession with evil. The darkness that Act one is enshrined in gives Iago the power he needs to plot against and deceive each character he communicates with. For instance he appears to be loyal to Othello whilst simultaneously uttering, “I hate the Moor.” Iago is Caucasian and is therefore referred to as having “white” skin. This purity and light that the colour white is associated with however, does not extend to his character as Iago is too consumed by dark thoughts.

He acts one way with Othello and another way behind Othello’s back. This is why even though he is deceitful and malicious the characters on stage refer to him as “honest Iago.” His two faced-nesses therefore give him the power he needs to plot and manipulate.
