Wallpaper - Medusa, Cobalt

Our Medusa, Cobalt wallpaper captures graceful jellyfish drifting through a deep navy ocean scene, rendered with the soft, fluid transparency of watercolour. The translucent bell shapes and delicate, trailing tentacles appear in muted shades of pale blue and white, offering an artistic contrast against the dark background. The organic spacing and floating composition give the design a calm, fluid visual rhythm across the wall. Produced as made-to-measure, PVC-free mural wallpapers with a subtle physical structure in the paper, this design brings an immersive marine motif into the home.

In the room

We see this design working especially well in a bedroom, where the deep navy ground creates an enveloping, quiet backdrop behind a bed. The gentle vertical flow of the tentacles helps draw the eye upwards, which makes the repeat feel natural on taller walls as well as across standard ceiling heights. In a living room, giving the wallpaper a wider uninterrupted wall allows the drifting jellyfish to be seen at scale without being broken up by tall storage. It also creates a distinctive atmosphere in a powder room or bathroom, where the marine theme feels right at home alongside clean wall mirrors and understated fixtures.

Styling it

Because the navy base is quite rich and the floating figures create plenty of organic visual movement, we like pairing this wallpaper with furniture that has clean, contemporary silhouettes. Lighter wood tones or muted painted surfaces help keep the space feeling open and balanced against the dark blue backdrop. Simple linen textiles in off-white or soft grey complement the watercolour quality of the jellyfish, letting the wall carry the primary visual interest without competing decorative elements.

Colour combinations

The design is built on a rich navy foundation with translucent accents of soft sky blue, pale cobalt and clean white. To complement the cool blue palette, we recommend painting adjacent walls or woodwork in soft chalky whites, gentle greys or muted stone tones. If you prefer a richer, more cohesive look, echoing the deep navy across surrounding trims or low cabinetry ties the entire room together effortlessly.
