On this black star-filled canvas, four brave, space-suited astronauts stand in unity. At the forefront, a friendly pioneer holds a futuristic device in their outstretched hands. Behind them stands a duo, in awe of the vast, unknown universe and of their incredible journey. To bring this scene to life, use a variety of different hues that capture the mysterious radiance of the stars. Add streaks of dark blues, purples and reds at the edges to create a heavenly backdrop. Dress the adventurers in cool jewel tones- a light blue, perhaps, for the front-most and a deep plum for the followers. Employ light-reflecting whites, silvers and yellows to illustrate the gleam of the suits and equipment. Let the creative spirit take flight and delight in the adventure of it all.
