In a world where design trends evolve at lightning speed, one movement is standing out by going back to basics: color. But not just any color—ton-sur-ton. This layered, monochromatic style is gaining serious momentum in modern interiors, and it’s easy to see why. The power of well-matched tones can completely transform a space, creating depth, personality, and harmony in a way no other design trick can.
With the rise of ton-sur-ton interior design, details matter more than ever. That’s where Jung comes in. Their LS 990 and LS 1912 switches, available in 63 rich shades from the Les Couleurs® Le Corbusier palette, offer designers and homeowners the ability to color-coordinate down to the smallest functional elements. From bold feature walls to subtly layered color zones, Jung’s precision-colored switches blend effortlessly into any interior—bringing both form and function into perfect balance.
Where Switches Become Design Features
At Bistro Goldmarie in Mainz, German design studio Lnid embraced a bold palette of deep greens and vibrant oranges. In this refined ton-sur-ton composition, Jung LS 990 switches in vert anglais pâle and orange vif echo the tones of the walls, ceiling, and custom furnishings. These switches don’t disappear—they elevate. Together with color-matched elements like the FSB 1267 and 4215 door handles, they create a space where every detail is in sync.


A Modern Take on Historical Charm
In the historic heart of Bruges, Belgian architecture firm Basil transformed a classic row house into a contemporary family home. The renovation retains its soul while embracing a fresh, nature-inspired design language. Multiple green zones weave through the space, unified by Jung switches in vert anglais—a standout from the Les Couleurs® Le Corbusier series. The result? A ton-sur-ton interior where light, structure, and detail converge seamlessly.


Color as a Sensory Experience
In Madrid’s buzzing city center, design studio Wanna breathed new life into a 1930s building with the opening of Hotel Bienvenir. From cool blues in the hallways to mango and blush tones in the rooms, each space tells its own chromatic story. Jung LS 990 switches in alpine white serve as the perfect visual balance—offering minimalist contrast while staying in harmony with the playful geometry and expressive colors throughout.


Design That Breathes with Nature
Tucked away in Menzenschwand, a picturesque village in Germany’s Black Forest, Haus am Hang is a vacation retreat where architecture flows with the landscape. Natural materials, clean lines, and calming greens define the interior. Here, Jung LS 990 switches in earthy tones enhance the ton-sur-ton concept, blending effortlessly into their surroundings. Every corner reflects the beauty of thoughtful color curation and mindful design.


Why Jung Ton-sur-Ton Is the Future of Design
In color-centric design, consistency is key—and Jung delivers it with surgical precision.
