Autumn Birch Wallpaper for a Warm Phone Lock Screen
autumn wallpaper · birch leaves · phone background · watercolor texture
Design a 9:16 portrait phone lock-screen wallpaper based on an autumn birch papel tapiz. Keep the upper quarter a quiet pale gray-blue sky with sparse fine branches, leaving clear room for the clock. Place golden birch leaves and slender trunks through the middle and lower areas, with richer color toward the bottom. Use layered watercolor washes, delicate paper grain, and a calm vertical rhythm. The palette should include honey gold, muted rust, olive, cream, and cool blue-gray. Avoid text, logos, watermarks, borders, and clutter around the upper screen. The mood should feel seasonal, gentle, and practical for a phone interface.
