Earth's brightest heroes are back in black-and-white, waiting for you to assemble their colorful costumes! All your favorites are in need of your pens, pencils and crayons - whether it's the red-white-and-blues of Captain America, the green skin of the Hulk or the Golden Avenger himself, Iron Man! Can you hit the target and stay in the lines like Hawkeye? Are you worthy to wield the right hue for Thor's uru hammer, Mjolnir? Will you address the red in Black Widow's ledger? Plus: Scarlet Witch, a Vision in green and more boldly clad adventurers! Don't forget the detailed backgrounds - like Black Panther's home nation of Wakanda, or the intergalactic stomping ground of Captain Marvel! But save a few of your darker shades for villains like Loki, Ultron and Thanos! Go to War on artwork by Marvel Comics greats - your choices are Infinite!
