Brown & Blue. A Palette That Never Goes Out of Style.

The collaboration between KOI Colour Studio and belarteSTUDIO continues with a second edition that celebrates one of interior design's most enduring color combinations. Introducing four new brown and blue colorways, this collection explores how timeless hues can create interiors that feel both contemporary and deeply rooted in tradition.

Inspired by Scandinavian restraint, historic textiles, antique interiors and architectural details, the new palette brings warmth, depth and serenity to artistic wall murals designed to live with you for years to come.

Rather than following trends, this collection embraces aesthetic sustainability—the idea that the most beautiful interiors are the ones that never need to be reinvented. 

Why Brown & Blue?

Few color combinations have remained as relevant throughout design history as brown and blue. Together they create a natural balance between warmth and calm, tradition and modernity.

Brown introduces richness, texture and a sense of grounding. It echoes wood, earth, leather and natural materials that make a space feel welcoming and lived in.

Blue brings lightness and clarity. It reflects the Scandinavian sky, water and historic pigments while adding a quiet architectural elegance.

Together they create interiors that feel layered, timeless and effortlessly sophisticated. 

Four New Shades Inspired by Nature & Heritage

This edition introduces four carefully developed colorways, each designed to work across the entire KOI collection.

Nordic Umber

A soft earthy brown inspired by Scandinavian pigments and natural materials. Warm without becoming heavy, it creates inviting interiors that pair beautifully with wood, linen and stone.

Wild Bark

A richer brown with organic depth, recalling aged timber, handcrafted furniture and historic interiors. A color that brings character while remaining timeless.

Blue Nocturne

A deep architectural blue that feels both dramatic and calming. It adds depth to a room while remaining soft enough to live with every day.

Bleu Patrimoine

A muted heritage blue inspired by traditional European pigments. Elegant, versatile and quietly expressive, it bridges classic interiors with contemporary Scandinavian design. 

Three Designs. Endless Character.

The four new colorways are available across three of KOI x belarteSTUDIO's signature wall murals, each offering a different interpretation of Scandinavian craftsmanship and decorative heritage.

Oslo Toile

A contemporary interpretation of the classic toile tradition, Oslo Toile transforms Norwegian landscapes, architecture and cultural landmarks into an artistic panoramic mural. Available in all four new colorways, it balances storytelling with timeless elegance.

Bold Stripe

A confident striped wallpaper where bold rhythm meets refined craftsmanship. The new blue and brown shades soften the graphic expression, creating a stripe that feels both classic and contemporary.

Still Garden

Inspired by the Arts & Crafts movement and Scandinavian simplicity, Still Garden combines stylised florals with structured repetition. The new colorways give the design a quieter, richer expression that brings warmth and character to modern interiors. 

Designed to Last

The second edition of KOI x belarteSTUDIO is built around the belief that timeless color is one of the most sustainable design choices we can make.

Brown and blue have returned throughout centuries of interiors because they adapt effortlessly to changing homes, materials and personal styles. They invite layering rather than replacing, allowing spaces to evolve naturally over time.

The result is a collection of artistic wall murals that feel equally at home in contemporary Scandinavian interiors, historic homes and modern spaces seeking warmth, personality and lasting beauty
