The girl in the drawing has an undeniably cool air about her. Her striking blue hair and eyes are striking against her black clothing. Her shirt features a stylized skull, giving her look a slightly spooky edge. Wrapped around her neck is a blue and black striped scarf, adding a colorful detail to the look. She completes the outfit with black leggings and blue and black boots.
To bring the image to life, start by coloring her outfit in deep blacks and blues. Include details such as the skull on her shirt to emphasize her look. Then, pick a brightly colored blue to bring out her blue hair and eyes. To make a contrast, you could color the scarf in darker blues and blacks, creating a subtle pattern. Finally, use a vibrant blue for the leggings and boots to provide a colorful accent to the coloring page.
