This coloring page features an intriguing maritime scene. At the center is a tall, white, cylindrical structure, framed by a metallic frame. Inside the structure is a large, glass dome. Around the sides, several small windows can be seen. Beside the tall structure is a large, yellow cylindrical object, and then a much smaller, blue object. Below all of this, there are several people in scuba gear, no doubt exploring the mysterious scene. To bring this image to life, use a light blue to create the sea around them. Make sure to provide a nice contrast between the yellow and blue objects, and to bring out the depth and texture of the white cylindrical structure and its metallic frame. For the people in scuba gear, choose some vibrant colors to really pop off of the page! Make sure to incorporate plenty of shading and highlighting to create a realistic and dynamic underwater scene.
