That is a very silly and funny picture. The silliest thing about the picture is that the baseball has a face that makes you laugh. Coloring this picture can be so much fun if you color it the right way.
You start with coloring the stars on side of the ball. The stars and the exclamation marks can be of two different shades of yellow. The area around the baseball can be of lighter shade of yellow.
The floor can be of brown color where as rest of the background can be given a light blue shade.
Once done with all that color the ball with a light grey and the tongue of the face of the ball can be of red color. Now come to the boy with the bat and color his cloths blue and orange and his face can be of a light yellow shade.
