Understanding Interracial Relationships - Is It About Color or Culture?

How do you define interracial? Is it someone who maybe dating a person from another culture? i.e. Latino/Asian or Caucasian/Asian I typically hear people referred to themselves as being mixed. - Is it based soley on color? i.e. Black/White - After all is said, are we talking about cultural differences or color?
