Wallpaper - Harlequin Prism, Sapphire

Designed by Nina Leth, our Harlequin Prism, Sapphire wallpaper reinterprets classic diamond geometry through bold, faceted planes and rich blue tones. Crisp angles meet painterly, mottled visual textures that add tactile depth across the composition, moving between deep navy and lighter denim blues. We love how the dynamic prism structure creates rhythmic vertical movement without feeling rigid or overwhelming. Like all our wall murals, this design is made-to-measure to fit your exact wall dimensions and printed on PVC-free paper with a subtle surface texture that is straightforward to hang.

In the room

The large-scale geometric facets give this design a confident graphic presence, making it especially effective on a main feature wall. In a living room or behind a bed, the rich sapphire palette anchors the space while the angled shapes draw the eye upward, accentuating ceiling height. We also see our mural wallpapers working beautifully in a dedicated home office, study, or library, where the orderly rhythm brings a focused, contemporary energy. In smaller areas like an entryway, hallway, or powder room, wrapping the walls creates an immersive, jewel-box feel.

Styling it

Because the geometric pattern carries significant visual energy, we suggest pairing it with clean-lined furniture and quieter materials that let the wall take center stage.

• Balance the cool blue tones with warm wood furniture, such as mid-tone walnut or natural ash, to soften the sharp geometric angles.
• Choose solid upholstery in textured neutral weaves or smooth leather rather than competing patterns, keeping the overall room composition grounded.
• Add subtle metallic accents in warm brass or muted bronze to introduce a refined warmth alongside the deep sapphire shades.

Colour combinations

The motif itself is composed of varied cold blue tones, ranging from inky midnight and deep sapphire to soft sky and dusty denim. When choosing colors for surrounding trim and adjacent painted walls, crisp off-white or pale chalky grey creates a fresh, high-contrast look that highlights the sharp geometry. For a more enveloping, dramatic mood, deep indigo or slate navy on neighbouring surfaces continues the rich blue palette across the entire room. If you want an accent color in cushions or decorative objects, warm ochre, rust, or soft terracotta creates a striking, balanced contrast against the blue facets.
