A simple, elegant iPhone wallpaper inspired by Apple's default designs, featuring a minimalist aesthetic with soft, muted tones like grayscale, beige, or light pastels. The image should avoid bright or flashy colors, focusing on subtle gradients and smooth transitions to create a calming and refined feel. Incorporate abstract shapes or gentle curves to add a touch of modern sophistication, but keep the overall design understated and clean. The image should resemble a high-quality Apple-inspired wallpaper, prioritizing simplicity, balance, and elegance without any distracting elements.
