Hispanics with mostly Caucasoid or Negroid features may not be recognized as such in the United States in spite of the ethnic and racial diversity of most Hispanic American populations. Hispanics who do not look like the stereotypical Hispanic may have their ancestral status questioned or even challenged by others. Actors Martin Sheen, Alexis Bledel and Cameron Diaz, for example, are Hispanic even though they may be presumed not to be so because, being white, they do not fit the stereotype. If Hispanics with mostly Caucasoid features are to be considered Hispanic, they have stereotypical Mediterranean/Southern European appearance - olive skin, dark hair, and dark eyes.
