Introducing Posidonia marine themed wallpaper collection

15 Dec 2025 PrivateTalky

Posidonia is a calm and serene marine inspired collection created as a soft tribute to the macOS Tahoe release and the Liquid Glass design language Apple introduced this year. After a year filled with glossy neon, vibrant gradients, and the shiny spectacular Pro collections, Posidonia arrives as a peaceful closing chapter. Probably the last collection of 2025, it captures the quiet beauty of seashores and brings a refreshing, atmospheric simplicity to your screens.

Design

Inspired by the gentle movement of marine plant grass, Posidonia wallpapers are built on deep color transitions and warm ocean toned gradients shaped by sunrise and sunset hues. Each piece gives a dimensional feeling to your space. Calm yet immersive.

The collection features two versions. One with depth and subtle blur that complements your workspace without distractions. The second is a more zoomed out view with clearer focus on the scene for users who want extra dimension and clarity.

Dynamic Scale

Posidonia includes a special dynamic macOS wallpaper designed to shift naturally throughout the day, reflecting changes in light from morning to night. Alongside it, the collection features a dedicated Light and Dark version that automatically switches based on your system appearance. You can also set any individual wallpaper separately, giving you full control over how Posidonia lives on your desktop.

Sea to Sky Colors

Posidonia’s color palette flows from marine blues to soft coastal greens, guided by the changing tones of the sky throughout the day. From sunrise warmth to sunset calm, each gradient is tuned to feel natural, atmospheric, and quietly immersive
