Examples of yellowface mainly include the portrayal of East Asians in American film and theater, though this can also encompass other Western media. It used to be the norm in Hollywood that East Asian characters were played by white actors, often using makeup to approximate East Asian facial characteristics, a practice known as yellowface. American media portrayals of East Asians have reflected a dominant Americentric perception rather than realistic and authentic depictions of true cultures, customs and behaviors. Yellowface relies on stereotypes of East Asians in the United States.
