I would color the Treasure Planet - Ship with a combination of rich blues and grays. Start by using a bright blue for the cockpit and wings, and a slightly darker shade for the solar sail. Use a medium gray for the cargo containers and a lighter gray for the main body. Finally, add some texture and texture to the entire ship by using white highlights and black shadows to give it an extra pop of dimension. To further enhance the ship, add a few stripes of metallic silver or gold along the wings and cargo containers. Overall, the combination of blues, grays, metallic silver, and gold will make the ship look clean and futuristic.
