Swiss Architectural Color

Viennese Red. French White. Bernese Sandstone. Queen Lucia Yellow.

180 handcrafted architectural colors, made in our Swiss manufactory from more than 120 natural and mineral pigments — blue stones, red earths, soft chalk, and artists' pigments rarely used today.

These are colors for architecture that does not shout. Colors of depth and quiet luminosity, mixed by hand with mineral binders that let walls breathe and respond naturally to changing light. Every ktCOLOR color gives walls, ceilings, woodwork, and facades a timeless presence — natural, enduring, and unmistakably handmade.

From 17 to 27 September 2026, ktCOLOR will be part of Zurich Design Weeks, Switzerland's largest design festival. At the House of Interior, we will present the installation Blau machen ("Making Blue") and host the evening talk Blau gestalten ("Designing with Blue"), exploring blue - one of the most powerful tools in architectural color design.

Throughout the festival, founder Katrin Trautwein and the ktCOLOR team will welcome visitors to guided tours of the installation, sharing surprising insights into the design principles behind blue and its influence on light, space, and perception.

Please note that all talks and guided tours during Zurich Design Weeks will be held in German. Design professionals interested in an English-language workshop are warmly invited to contact us. We will offer workshops in English at our Swiss manufactory from January 2027 onwards.

The infinity of Ultramarine. The depth of Umbra. The luminosity of Rügen Chalk. The heritage of Veronese Green.

Our color consulting follows a clear methodology. We analyse light, space, and architecture to develop architectural color concepts that create atmosphere, establish spatial hierarchy, and give buildings their identity. Our expertise in rare natural and mineral pigments, their material qualities, and their interaction with light provides a solid foundation for confident color decisions and clear communication with clients, architects, and contractors.

Whether you need guidance for a single color decision or a comprehensive architectural color concept, we tailor our consulting to the requirements of your project. We would be pleased to help you find the consulting format that best suits your needs.

A screen creates color with light. A handcrafted color card shows pigments.

Handcrafted color cards and paint samples filled with our original colors are among the most important tools in architectural color design. What you see is what you get: they reveal the materiality, depth, and interaction with light exactly as the color will appear in your project. A screen cannot do this. It creates color with light, not with pigments. Our color cards and paint samples provide a reliable foundation for confident color decisions and are available for every ktCOLOR Architectural Color in our online shop.
