Leopards are tan to yellow with black markings. Though people think of leopards as having black spots, they actually only have spots on the face, feet and lower legs. The rest of their dark markings are spots forming circles (or rosettes). Some leopards are black, even among a family of yellow leopards, but underneath the black, the darker black spots are still there!
