This coloring page depicts a stoic and powerful figure with dark skin and a bald head who is ready for action. The man, who looks deep in thought, has a bright green tattoo on his face and chest. He wears a bold red loincloth, and a large knife is clasped in his right hand. His gaze is directed straight ahead with his eyes closed in concentration, as if he has a big challenge ahead.
To bring the image to life, I would use bright shades of yellow and red to color in the tattoos and loincloth. The man's skin could then be painted in different tones of brown. I would also use contrast to make the knife shine by utilizing short and quick lines of grey shades. To make the man appear powerful, use a black for his eyes and outlines of strong, bold shapes.
