This coloring page shows an idyllic coastal scene, with a large gray and white fishing boat docked at a pier. In the foreground, there is a small blue and white boat, with both boats' sails furled. Along the pier, people can be seen walking and enjoying the view. Sea gulls fly overhead, adding to the sense of peace and serenity. To bring out the color and detail of the scene, I'd start by painting the boats with a light gray and while, while shading in the details with mid-toned gray. The sails should be white with gray shading in the folds. Light blue and white can be used for the smaller boat, and pastel yellow can be used for its sails. For the people, use a beige for skin tones and a darker blue for their clothing. The sky should be a light blue, with a few white clouds, and a few yellow seagulls. If desired, a touch of pink and orange can be used for the sunset sky. Finally, the pier should be a light wood color, with white for its railings.
