Octavia Butler's Fledgling, Daniel Jose Older's Shadowshaper, and Nalo Hopkinson's Sister Mine are considered YA and have black protagonists. (Fair warning, Sister Mine has a brief incestuous sex scene that skeeves out some readers, me included. The Caribbean-influenced magic is pretty neat, though.)
Justine Labalestier's Liar has a biracial protagonist and includes fantasy elements (although it's up to the reader to decide if they are real, as the narrator is extremely unreliable).
Kate Elliott's Court of Fives also has a biracial protagonist, this one in a secondary-world setting.
