The Colour Concept: one finish across every detail
Quincalux x Jullight x SUMUM
Every interior is shaped by its larger gestures. The architecture, the materials, the light, the proportions.
But often, it is the smallest detail that determines whether a space truly feels complete.
With The Colour Concept, SUMUM's finish language extends beyond switches, outlets and reading lights. Together with Quincalux and Jullight , this language is carried further into door hardware, cabinet hardware and lighting, exploring how one refined finish can bring every detail into the same visual rhythm.
One finish. Across every detail.
Three Belgian manufacturers, one shared vision
Quincalux, Jullight and SUMUM each approach architectural detail from their own expertise.
At the centre of The Colour Concept is SUMUM’s approach to refined architectural hardware: pure forms, carefully developed finishes and a calm material language across switches, outlets and reading lights. Quincalux extends this language to door handles, cabinet hardware and other refined interior fittings, while Jullight adds light to the story with handcrafted architectural and decorative lighting that brings warmth, atmosphere and identity into a space.
Together, these three Belgian manufacturers share the same belief: that interiors become stronger when the details are treated with the same care as the architecture itself.
The Colour Concept brings this vision together in one finish palette, allowing architects and designers to specify architectural hardware and lighting with greater cohesion, clarity and confidence.
About Quincalux
Quincalux is a Belgian manufacturer of high-end architectural hardware, known for door, window and furniture fittings crafted with a strong focus on quality, materiality and detail.

About Jullight
Jullight is a Belgian architectural lighting producer creating handcrafted lighting pieces in high-quality materials such as bronze, brass, leather and ceramics.
Their work brings together light, craft and atmosphere, with fixtures that feel subtle, sculptural and deeply connected to the spaces they inhabit.
Crafted with precision
Behind every finish lies a precise process.
Each surface is prepared, refined and treated with care. Some finishes are shaped through patination, where timing, temperature and material reaction determine the final depth of colour. Others rely on subtle brushing and protective finishing to preserve the natural character of the material.
The result is never flat or generic. It is layered, tactile and alive.
That same devotion to craft continues through Quincalux and Jullight. In Wevelgem, Quincalux transforms raw brass into refined architectural hardware almost entirely in-house, from machining and polishing to sandblasting, surface treatment and varnishing. Jullight brings craftsmanship into the world of lighting, with fixtures that are handcrafted, precisely cast and finished as tactile pieces in bronze, brass, leather, linen and ceramics. Different disciplines, different objects, but the same attention to material depth, refined finishing and the quiet power of detail.
