The large, metal object in the center of the coloring page is an interstellar spacecraft, ready to explore the depths of space. The long, thin piece attached to it is its rocket booster, giving the crafts its powerful propulsion. Beyond the craft is a great expanse of stars and planets, including the large planet augmented by the craft's journey. To bring this scene to life through coloring, consider using warm shades of blue and purple to make the planets stand out against the dark backdrop of the starry universe. For the metal craft at the foreground, mix silver and white to give the piece a metallic sheen. The exhaust from the rocket booster should be bright red, to contrast sharply against the cool colors of space. With these colors, you can bring this interstellar journey to life!
