This coloring page features a heart surrounded by thorns or barbed wire. The heart has a piercing that is rending the heart in two. The background is a deep, foreboding black, creating an atmosphere of sorrow and distress. To fill in this image, I would use a muted palette of dark blues and greys, with a bright red for the heart itself. The heart should be defined by strong red lines, while the piercing is highlighted with a contrasting color to make it stand out. To emphasize the feeling of the image, I would use harsh, grayscale shading to create a sense of barrenness and emptiness.
