When coloring Lanturn, you could use bright and cheerful colors to give it a lively, friendly feel. Begin by painting its body blue and its head yellow, making sure to keep the edges of each color crisp and neat. For its large black mouth, use a darker shade of blue, and for its eyes, use a light yellow for the iris and deep black for the pupils. For its two long, orange fins, use an orangey-red, and for its tail, you might try a combination of blues and oranges to give it a striped pattern. Lastly, use a combination of black and deep blue to outline Lanturn's body and head to provide a nice, finished look. With these colors, Lanturn will look shy yet awe-inspiring, living up to its mysterious lure.
