On the surface of the moon, Dunno and the computer stand side by side in silent contemplation, gazing out at the vast expanse of the glittering Earth before them. Dunno's fur stands out with a bright blue, alluding to their extra-terrestrial surroundings. The computer has a dull yellow-green hue, suggesting its synthetic nature, and is talking to Dunno with curious enthusiasm. You might choose to color the moon beneath them a pale gray, with a wash of white suggesting its rocky terrain, and the dark night sky a deep black. The Earth below could be colored in with a myriad of blues and greens, for its enchanting landscapes and oceans, followed by a band of white clouds, buffering the blue and green hues beneath.
