In this cheerful and colorful scene, a group of people wearing brightly colored space suits and large helmets are standing in a room and holding hands. They all appear to be looking up at something with wonder and curiosity. To give this scene an exciting and mysterious atmosphere, you could use bright neon shades for the space suits and a light grey or pale blue for the helmets. Additionally, the walls behind them could be painted a deep royal blue. To make the people stand out the most, you could use a yellow or orange to give their suits a warmth and brightness. Use a light blue or green to emphasize the faces of the people and to give this image a magical, otherworldly vibe. Finally, add popping bursts of stars and galaxies to complete the space-like effect.
