The Hulk is a powerful and intimidating figure, depicted in a vibrant green and brawny figure. His raging strength is often unleashed with one hand pressing against his tattered shirt, and the other ensuring that whatever feat of strength he is about to take on, will be completed. Coloring this image, I’d suggest using shades of green that are bright and alive. Paint his iconic tattered clothes variations of dark blues and blacks, with hints of deep red added to depict the worn and torn state of his attire. Let his bulging muscles be accented by lighter greens and details of white to suggest individual muscles and veins. Finally, add accents of yellow to the character to portray his power and energy, ensure to contrast the lighter shades with the darker for a vibrant and realistic effect.
