A vibrant, abstract phone wallpaper featuring a close-up, highly detailed macro shot of a single, iridescent soap bubble. The bubble’s surface shimmers with an interplay of sapphire, emerald, and ruby hues, reflecting a distorted, miniature cityscape in its depths. Tiny, almost imperceptible water droplets cling to the bubble's underside, adding textural complexity. The background is a soft, out-of-focus gradient of deep indigo transitioning to a pale lavender, creating a dreamy, ethereal atmosphere. The lighting is soft and diffused, reminiscent of a sunlit morning. The style is hyperrealistic with a painterly quality, evoking a sense of wonder and tranquility. The composition is centered, with the bubble occupying approximately 70% of the frame. Shot with a macro lens, emphasizing the intricate details of the bubble's surface tension and color variations. The overall mood is serene and calming, perfect for a phone background. Render in the style of a highly detailed scientific illustration blended with contemporary abstract art. Employ a shallow depth of field to further emphasize the bubble and its reflective properties. Texture is paramount; the bubble's surface should appear smooth yet subtly irregular, with visible reflections and refractions.
