as noted, yellow journalism started in NY, and NY had laws concerning miscegenation on the books till the 1960's! and most were aimed at asian/white mixed marriages, not black/white. California was not alone in being afraid of a yellow peril..

traces still exist, and there is good deal of resentment against the new asian communities.. be they japanese (smallest), chinese, (middleing) or korean (largest asian group in NYC).
