This coloring page is an exciting scene of the Avengers ready to defend their city from the looming threat of a large black panther. Set against a cityscape ablaze with orange flames, this scene is full of action and demand for bold colors. For the panther, opt for deep blues and grays for its fur, as well as warm yellow and oranges for its eyes and flames. For the Avengers, bright oranges, reds, blues, and greens could be used to show their united strength and determination. Captain America's shield could be a metallic color, and Iron Man's arc reactor a brilliant white. Finally, the dark gray and green of the Hulk's skin could bring a darker hue to the page, emphasizing the danger and power of the panther.
