The page depicts Tony Stark, a brave and brilliant superhero who also goes by the name Iron Man. A brilliant inventor and CEO of Stark Industries, Tony Stark is a genius scientist and engineer who has created some of the world's most advanced technology. He is not only a skilled businessman, but is also the founding member of the Avengers.
When coloring this page, I would start by giving Tony's suit a metallic, reflective sheen in various shades of red and gold. His eyes can be shaded grey or black, and I would accentuate his vivid and determined expression with splashes of deep blues or purples. His signature arc reactor could be shaded with a glowing, white center, surrounded by a faded grey background. Stark Industries' logo can show up twice in a vibrant and striking gold or silver that handily contrasts the suit in deep reds and oranges. Furthermore, the background of the page could be filled in with a nice, earthy tone of yellow-green, making the contrast between Tony and his environment more vivid. Finally, to make the page stand out, I would include a shadow around the figure to give it a more 3-dimensional look.
