This coloring page depicts a hero figure standing atop a busy city skyline. He is wearing a smart gray suit and a flowing black cape, and a yellow belt with a bold black bat symbol. He has a serious expression and the power of justice emanates from him as he holds a black and gray gun in his right hand.
As for how to color him, consider a strong contrast between the figure and the cityscape. Choose dark and light shades of gray for his suit and cape, and a brilliant yellow for his belt. Brighten up the city around him with oranges and blues to make him stand out even more. For the bat symbol, use black to make it pop against the yellow belt, and for the gun use contrasting shades of black and gray. With these colors, the hero will stand out against the city backdrop and really draw attention.
