Wallpaper - Koi Fish, Denim

Our Koi Fish wallpaper in Denim, created with Blue Bee Studios, brings an aquatic motif to the wall with stylized swimming fish set against a deep navy background. The composition balances light blue and white gradients across the flowing fins and tails, giving the fish an organic sense of movement and visual depth. Small green dots and delicate curving lines in olive and light blue drift between the forms, lending the seamless repeat an artistic, fluid rhythm. Made to measure on our PVC-free paper with a subtle surface structure, our mural wallpapers bring a considered, graphic presence to any interior.

In the room

In a bathroom, poolhouse, or cloakroom, this design creates an immersive, wrap-around atmosphere. The dark navy ground gives the pattern visual weight, while the light blue highlights keep the repeat lively and rhythmic across multiple walls. We also like this wallpaper behind a vanity unit or on an accent wall where the fluid linework can be appreciated up close. In spaces with softer, diffused light, the deep navy base recedes quietly, allowing the lighter blue curves and olive details to stand out with understated clarity.

Styling it

The Art Nouveau-inspired curves and heritage feel of this wallpaper pair naturally with classic and French country design elements. We would balance the dark navy backdrop with warm off-white painted woodwork or paneling, which helps frame the repeat and keeps the space feeling open. Unlacquered brass or antique bronze hardware works especially well against the cool blue tones, introducing a subtle metallic warmth that complements the fluid, decorative lines of the fish.

Colour combinations

The design is built around a dark navy base layered with denim blue, soft sky blue, white, and subtle olive green accents. When choosing paint for adjacent walls, doors, or architraves, muted pale blues and warm chalky whites create a harmonious, tone-on-tone setting. For a more grounding contrast, deep slate tones or muted moss greens pick up on the smaller organic details within the artwork without competing with the navy backdrop.
