Wallpaper - Echinoderms, Dark Blue

Our Echinoderms, Dark Blue wallpaper brings an artistic look to the wall with an illustrated motif of sea creatures. Designed by RNM Arts, the pattern features five-armed starfish and detailed sand dollars floating over a deep dark blue ground, drawn with clean lines and delicate stippling in sea green and light turquoise tones. The floating layout gives each marine element breathing room, creating an expressive rhythm with a screenprint-inspired character. Produced as made-to-measure wallpaper murals on PVC-free paper with a subtle surface texture, this design brings a fresh coastal look to any interior.

In the room

We see this wallpaper working especially well in spaces where you want a moody yet fluid atmosphere. In a bathroom or a powder room, the deep blue backdrop and aquatic motifs feel completely at home, transforming a smaller room into an immersive sanctuary. Because the starfish and sand dollars are scattered rather than locked into a rigid grid, the motif also flows effortlessly across uninterrupted walls in a bedroom or a coastal vacation home. The high contrast between the pale turquoise line work and the dark background ensures the details remain crisp and captivating, even from across a larger living space.

Styling it

When styling around this design, we like pairing the deep marine tones with natural, tactile finishes that balance the dark backdrop. Warm woods like teak or natural oak bring warmth to the space, keeping the cool blue palette grounded and inviting. For decorative accents, consider off-white ceramics, simple woven baskets, or brushed brass hardware, which catches the eye cleanly against the dark wall murals. Keeping larger furniture relatively tailored and understated lets the graphic details of our mural wallpapers take center stage without visual clutter.

Colour combinations

The design itself is anchored by a deep navy and dark blue base, highlighted by sea green, light turquoise, and soft earthy accents within the linework. To complement these shades on surrounding painted walls or trim, consider using a soft, muted off-white to create a crisp and fresh outline. If you prefer a richer, more continuous look, adjacent walls painted in a deep marine navy or a dusty slate green will create an enveloping, cohesive palette.
