No, it doesn’t. In fact, most of the time in the US, “skin color” is code for race/ethnicity. Light-skinned Black people, White non-Hispanics, mostly-White Hispanics, Native Americans, and Asians can have very similar or even identical literal skin colors; but the Black person is still Black, the Whites are still White (except maybe the Hispanic ones), and the rest are neither White nor Black.
