This beautiful and romantic illustration depicts Wall-e and Eva having an intimate moment together. She reaches out to him, her hand holding a delicate flower in its palm. He is reaching out towards her, his metal finger tips almost touching hers. In the background, the Captain looks on with a smile, perhaps wishing them clear skies and happiness on their journey. To color this picture, I recommend starting with Wall-e's boxy shape, filling it with a light, metallic blue or green. Eva can be a vibrant yellow or pink, with a green flower in her hand. For the sky and the back of their small spacecraft, a bright and cheerful blue could be used. For a finishing touch, the captain can be a thoughtful shade of blue or purple.
