This creative space scene lends itself to a wide array of coloring ideas. All the figures can be given a unique color scheme to really make them stand out. Bright blues and purples are an excellent choice for the astronauts and their distinctive space suits. The console screens might look great with a black or grey background to maximize the 'in space' feeling. The raised platform and surrounding area could take on a metallic dark yellow or gold, while the area around the two arguing figures might feel more energized in a vibrant orange or red. Experiment with different shades and combinations to create a truly unique and eye-catching image!
