Complex coloring pages - Happy Birthday ! (21 coloring pages)
Advanced or expert coloring is intended for older children, teenagers and adults with coloring experience. They have smaller, more intricate designs to fill in with color, which can take a lot longer than simpler colorings. Advanced colorings may also have very fine lines or very fine details, which may require great attention to detail. These coloring pages can be very relaxing and stimulating for people who like to spend time focusing on a creative task.
