Batman stands tall and proud atop a rooftop, facing the night sky and the vast expanse of the city below. His cape is rippling in the wind, setting the mood for a vigilant and powerful protector. His cowl casts a dark shadow over his eyes and reflects the determination on his face. For this coloring page, I would suggest using deep blues and blacks to capture the mystery and strength of Batman. Avoid using too many bright colors to keep the mood of the page. Incorporate small bits of orange and yellow to depict the lights of the city and to bring the Batman's features to life. Additionally, I would use gray to provide more definition to the shadows of the cowl and the cape, as they migrate across his body. With these colors, this Batman can be brought to life and will truly have the look of a guardian of the night.
