Wallpaper - Cobalt Metropolis

Our Cobalt Metropolis wallpaper captures an electric city skyline at twilight, photographed by Joseph Sohm. A deep, vivid cobalt blue sky forms a graphic backdrop to illuminated skyscrapers, where warm copper, amber, and cool green reflections glisten across glass facades. The distinctive silhouette of Reunion Tower with its illuminated geodesic sphere rises proudly alongside sharp triangular and stepped architectural forms. Printed to your exact dimensions, our PVC-free mural wallpapers have a subtle physical structure in the paper that brings depth to this dynamic evening vista.

In the room

Because this is a wide, panoramic architectural composition with strong vertical towers, we would give this design a generous, uninterrupted wall where the full skyline can unfold naturally. It makes an impactful statement in a contemporary living room, placed behind a low-backed sofa so the lit facades and glowing tower remain entirely visible. The clear contrast between the dark blue sky and bright illuminated windows gives the space an atmospheric evening presence, working especially well in rooms where you want to introduce depth and urban energy without cluttering the floor space.

Styling it

We recommend letting the architecture lead the room by pairing the design with clean-lined, modern furniture. Low-profile seating in charcoal, deep navy, or warm grey allows the skyline to sit as the focal point without competing for height.

To balance the cool cobalt tones, incorporate warm metallic accents such as bronze or brushed brass in lighting fixtures, alongside smoked glass or sleek black metal coffee tables. These reflective surfaces echo the lit glass panels of the skyscrapers and reinforce the sophisticated urban character of the mural.

Colour combinations

The palette is built around intense cobalt and royal blue, contrasted with warm sunset-orange reflections, golden amber window lights, and minty neon green outlines.

For adjacent walls and skirting, deep slate grey or moody navy creates an enveloping, dramatic interior. If you prefer a lighter contrast, a crisp cool white or pale mineral grey keeps the room feeling open while allowing the blue sky in the wallpaper to stand out vividly. To pick up on the architectural reflections, small decorative accents in burnt orange, cognac leather, or warm bronze tie the entire room together effortlessly.
