There is no novel of Othello, actually. The famous Othello is a play by Shakespeare. Plays are not novels.
If Othello was white, Othello wouldn't have been insecure, his relationship with Desdemona wouldn't be disapproved of and Iago might have hated Othello less.
That is, of course assuming that Othello is white and so is everybody else. If Othello were white and everyone else was black, the story would be much the same because Othello's insecurity stems from his feeling of otherness, his feeling that he was different from everyone else. Othello has in fact been staged in this way, with a black cast and a white Othello. It has also been staged with actors playing Othello who are not black but are different from the rest in some other way.
Desdemona, a white Venetian lady.
Othello strangles Desdemona and then Emilia comes in and Iago kills her and then Othello realizes that Desdemona was innocent so in the end he kills himself. Not a happily ever after ending, eh?
Desdemona is in many ways the opposite of Othello: of an old established Venetian family, white, inexperienced and very young. Othello is middle-aged, black, widely experienced and a man without any pedigree at all in Venetian society. Her differentness may have attracted him to her at the outset, but he must also have noticed her wonderful openness, clarity of vision, unshakeable fidelity, courage and kindness. These characteristics would win him for longer than just her novelty. The idea of being attracted to someone different as a novelty is used by Iago to undermine Othello's self-confidence. Iago tells Othello that once the novelty wears off, Desdemona will turn from Othello to other men, and Othello, who is a very humble man, is tempted to believe this because he does not see the many virtues which Desdemona really loves him for: his wisdom, experience, humility, equanimity, courage, fair-mindedness and his deep and genuine devotion to her.
"an old black ram / Is tupping your white ewe" Act 1, Scene 1
That'd be Othello
Desdemona, a white Venetian lady.
She married him. Mind you, Othello must have been the world's most diffident wooer; he had no hope in his mind that someone that young and aristocratic and white would go for a guy as old and common and black as he was. But she did.
