Two pool balls sit on a gray table with shadows.
An indoor close up view of two pool balls. The pool ball to the left is all white and known as a scratch ball. The ball to the right is all black with a small white circle in the middle of it. There is a black number "8" in the white circle. This is an 8 ball. The 8 ball has a small scratch on it. Both pool balls are sat on a grey pool table and are casting shadows onto the table due to a light illuminating from above.
