This coloring page is full of vibrant colors and fun characters. The two trolls featured have distinct personalities just based on their eye and hair colors! The blue troll has a special purple hairdo and the green troll has an eye-catching fiery orange mohawk. Both trolls have cheerful yellow eyes, big noses, and curvaceous smiles.
My advice for how to color this page would be to choose bright and cheery colors to best bring out the characters' personalities. For the trolls, pick a few different shades of blue and green to create some contrast. For the hair, use several different tones of purple and orange to make the hairdos pop. Finish off the trolls with warm yellows for the eyes, pink for the cheeks, and white teeth to really show off those mischievous smiles.
