I’ve always been amused that some Black people have the surname “White”.
White, Black, Gray, Silver, Gold, Green, Blue. All surnames. I don’t know of any Reds or Yellows. I think there are Redds with 2 “d”s though.
You forgot about Brown and the less common Orange. Prominent DC politicians include Mayor Vincent Gray, his top aide Lorraine Green, DC Councilman Vincent Orange, and DC Council Chairman Kwame Brown (not the former Wizards center): all are black, but none are surnamed so.
The 1983 Kansas City Royals had Frank White, who is black, Bud Black, who is white, and Vida Blue, whose skin color is more of a dark purple.
