Reminds me of the "one drop rule" in America, which I don't agree with. I think of Obama as mulatto if I had to describe him.

"Many people in the United States are rejecting the one drop rule and are questioning whether a person with one black parent should be considered black or biracial. Although politician Barack Obama self-identifies as black, 55 percent of whites and 61 percent of Hispanics classified him as biracial instead of black after being told that his mother is white. Blacks were less likely to acknowledge a multiracial category, with 66% labeling Obama as black.[44] Forty-two percent of African-Americans described Tiger Woods as black, as did 7% of white Americans."
