Italian Colour remains part of the material
Control changes the state of transparency, not an arbitrary colour. The pane therefore keeps a consistent identity both as a clear partition and as a frosted surface.
Switchable coloured active glass
DGF Colour. Transparency that shapes the interior.
Active glass in colour variants combines privacy control with a distinctive design effect. Colour is not an accessory; it becomes part of the material palette.

DGF solution
Technology that does not need to be hidden.
DGF Colour switchable active glass adds a considered colour effect to switchable glazing. The pane still controls privacy while shaping atmosphere and recognition.
The final variant follows light conditions, surrounding materials and the desired effect. Samples are part of the design decision because perceived colour depends on context.
Best suited to:
- Hotels
- Showrooms
- Premium offices
- Bespoke interiors
How the solution works
Colour, transparency and light must be assessed together.
DGF Colour combines the active layer responsible for switching between clear and frosted states with a selected colour effect. The colour is not a digital filter changed in an app. It is a property of the prepared glass composition, selected for the materials, lighting and scale of a particular interior.
The same sample will look different against a pale wall, dark joinery or a brightly lit lobby. Switching state also changes how light is diffused. For this reason the colour variant is confirmed on a physical sample and assessed in two views: active glass and frosted glass.
Important: a phone screen or visualisation cannot reproduce the colour and transparency of glass faithfully. The final decision should be based on a physical sample viewed beside the intended materials and in comparable light.
Light changes perception
Light temperature, sun direction and the background affect saturation and depth. We therefore assess the glass in daylight and artificial light, not only on a white sample table.
The frosted state creates a different surface
When PDLC scatters light, the colour reads more like a surface than a transparent filter. This can become a deliberate accent in reception, wellness or display areas.
Consistency requires one approval reference
For several panes we define one approved variant and reference. Dimensions, installation orientation and surroundings should be documented together so the glazed field reads as one composition.
What you gain
Technology that follows the space.
The result is not defined by one parameter. It comes from the right pane, considered controls and installation detailing.
Colour as a material
The pane joins the interior palette instead of remaining a neutral background.
Two levels of expression
Switching state changes privacy and the perception of colour at the same time.
A confirmed variant
Selection is confirmed on a physical sample viewed in the project context.
Consistent integration
Power and controls are planned as carefully as the interior detailing.
From concept to commissioning
One point of responsibility. Three clear stages.
-
01
Define the intent
We define the role of colour, light conditions and adjacent materials.
-
02
Compare samples
We assess the clear and active states, ideally in the intended surroundings.
-
03
Produce to size
After sample approval, we engineer the pane, cable exits and control method.
Space and purpose
DGF Colour works where technology should also shape the identity of a place.
A coloured pane should not be an arbitrary special effect. The best results come from the interior palette, usage and how the glass appears in both states throughout the day.
Hotel, apartment and wellness
Privacy matched to the atmosphere
A partition beside a bathroom, spa or suite can retain a subtle tone matching timber, stone and metal when clear, then become a calm coloured backdrop when switched. The sample should be assessed in daylight and evening lighting because a hotel night scene can change colour perception completely.
Reception, showroom and display
An active surface as part of the identity
In a reception or showroom colour can organise zones, reinforce the brand palette and change the character of a display backdrop. Viewing distance matters: a small sample shows the hue, but only an assessment of the full area helps set its intensity within the whole interior.
Home and bespoke interior
Glass that does not look like technical equipment
At home the hue can relate to joinery, textiles or metal so the active pane becomes part of the material language. It must be viewed from both rooms: the same partition may have a pale background from the living room and a dark one from the dressing room, changing its appearance.
A project, not a gadget
Colour must be judged in motion, light and both states.
That is why the decision is not based on a tiny swatch. We present a physical sample, switching action and the way the material responds to light before producing the final pane.

Informed selection
Selecting DGF Colour is material specification, not choosing a colour on screen.
The hue must be considered in relation to area, light and neighbouring materials. This process separates intentional design from an accent that only looked convincing in a visualisation.
Start with the material palette
Provide samples or references for key finishes: metal, wall covering, stone and joinery. Glass colour is selected as part of that composition.
Assess both states
The same variant must work as a transparent layer and a frosted plane. Assessing only one state creates surprises after commissioning.
Account for light throughout the day
Record daylight direction, luminaire temperature and evening scenes. The glass colour will interact with all of them.
Use restraint at large scale
A hue may feel subtle on a sample but dominate across many square metres. The size of the glazed area affects the selection.
Solution family
Choose the glass for the decision it needs to support.
Not every project needs the same configuration. Compare the core roles and confirm the details during consultation.

Questions before a project
Clarify first. Quote second.
Pricing depends on dimensions, pane count, controls and installation. A few answers usually identify the right direction.
01Does the colour look the same in every interior?
It changes slightly with light and surrounding materials. That is why we confirm the variant on a physical sample, not only on screen.
02Does DGF Colour still provide privacy?
Yes. It is switchable active glass enhanced with a colour effect.
03How does colour selection begin?
With a short consultation covering room function, light, the material palette and the desired character.
04Can the glass colour be changed freely in an app?
No. Controls switch the glass between clear and frosted states. The selected colour effect is part of the physical pane composition and is therefore confirmed before manufacture from available variants and a sample.
05Why can a sample look different after installation?
Perception is affected by surface area, background colour, light direction, luminaire temperature and viewpoint. The sample should therefore be viewed beside the intended finishes and in both glass states.
06Will several panes form a coherent surface?
They are designed as one set with a shared approved variant, but structural joints, different backgrounds and lighting can affect each field. Pane layout and installation orientation should be documented.
07Can DGF Colour be matched exactly to a RAL reference?
It should not be assumed to match an opaque paint or printed RAL reference exactly. Glass interacts with light, background and transparency, so selection is based on available variants and a physical sample viewed beside the intended finishes.
08Does the colour reduce daylight in the room?
Each colour composition affects appearance and light transmission differently. Area, orientation and background also matter, so there is no single universal result; the appropriate variant is confirmed with a sample and the project context.
09What determines a DGF Colour quotation?
Price depends on pane dimensions and quantity, the selected composition, glazing build-up, samples, framing, power, controls and installation. For larger surfaces, pane layout and sequence are also part of the scope.
