This coloring page features a giant purple and black alien looming over a small green monster, its hand tightly clasped around the frightened creature. The background of this scene is a sprawling city with tall buildings towering in the night sky. Above the buildings, a full moon shines brightly, casting its light onto the alien and its terrified companion. To bring out the looming nature of the alien, one should color the figure in dark shades of purple and black. Meanwhile, the small green monster should be a lighter green to make it pop off the page. Finally, blues and whites should be used for the night sky and the tall buildings as they provide a great contrast to the darker tones of the alien.
