This question relates entirely with Michael's experiences in Sicily (and specifically, Corleone.) Michael himself had grown to know who he used to be, and understand who he was becoming in Sicily himself. What needed to be known was that Michael was moving on from his old life. He could not be the Michael he used to be, after murdering a police chief (McClusky) and a drug dealer (Sollazzo.) He was now heavily a part of the affairs of the mafia. This is what drove Kay and Michael apart. He was changing, and she continued speculating from afar.
Kay, being in New York City, and Michael, being in Sicily, were so far apart physically and emotionally, that it was hard for Kay to be able to interfere with her boyfriend's affairs, and speculate over his business and family. Kay was also one of the strongest ties to his old life, the one he lived before crossing the threshold. Kay fell in love with a very simple, independent man; a war hero. That war hero had transformed into one of the main men of the Corleone family mafia; almost a complete polar opposite of who he used to be. This being noted, Kay was nothing but a distraction from reality, and a desire, rather than a need to Michael. She wasn't able to help Michael at all, but rather, cause harm, because, again, she was that sole connection to the Michael before the family business interfered with his life.
After the year Michael spent married to Apollonia, he went back to Kay in New York. But in the first scene that viewers saw Kay and Michael together in, after a very long time was drastically different from the previous. Kay was seen in a very dull beige trenchcoat. But why was she wearing a colour other than red?
In the previous post about the "Scarlet Woman", she was described as a desire, a lust, and an abomination. Perhaps, before, Kay wasn't a necessity to Michael, but more of a mere desire. She did not make him a better and stronger person. After the death of Apollonia, it is evident that Michael needs the support of another woman. This is where Kay comes in. Because she is no longer a mere desire to Michael, but a lifeline, she is not considered a "Scarlet Woman." She does not distract Michael from what he needs to do.
Kay Adams is a very interesting and complex character in the story. This is because the audience, and I myself, are able to connect with her more than we are able to connect with the rest of the characters. Kay is a mere speculator, fascinated by the cat-and-dog chase of the mafia. But what is even more interesting is exactly how much she grows as an individual, and how important she is to Michael, throughout the second half of the film.
