Good article on "colorism" in America:

The Senate leader [Harry Reid]’s choice of words was flawed, but positing that black candidates who look “less black” have a leg up is hardly more controversial than saying wealthy people have an advantage in elections. Dozens of research studies have shown that skin tone and other racial features play powerful roles in who gets ahead and who does not. These factors regularly determine who gets hired, who gets convicted and who gets elected.

Consider: Lighter-skinned Latinos in the United States make $5,000 more on average than darker-skinned Latinos. The education test-score gap between light-skinned and dark-skinned African-Americans is nearly as large as the gap between whites and blacks.
