Spider-Man is a superhero with superhuman abilities. He often wears a signature red and blue costume, with a black mask to conceal his identity. This picture shows Spider-Man swinging through the streets of New York City, ready to fight crime. To give Spider-Man dimension, you can color the costume with shades of both red and blue, so the costume appears to be 3D. The web-shooter on his wrists can be colored bright yellow, and his signature mask can be black and white. You can also add texture to his costume by shadowing some of the red and blue areas with lighter and darker shades. You can color the New York skyline around him in shades of mauve and purple, to give the background an imaginative feel. Finally, you can color the sky with a light blue and white gradient to complete the picture.
