As managing director at Silka, Asa McGillian works closely with installers supplying aluminium systems into modern homes every day. With colour central to many design-led projects, he shares what the trade is seeing on the ground and how curated palettes are changing the sales process.
Access to a wide range of RAL colours has long been a key selling point in windows and doors, giving homeowners complete freedom to personalise their homes.
Homeowners today are more design-literate and more decisive about the look they want to achieve. They still value choice, but they don’t want to be overwhelmed by it. While access to the full RAL spectrum remains important, what’s helping installers sell with confidence is the availability of curated colour palettes – finishes that have been carefully selected to work well together and suit a range of homes.
By offering a considered range alongside full flexibility, installers can guide conversations more effectively, helping customers visualise outcomes rather than compare individual colours in isolation. It shifts the discussion from ‘what’s available’ to ‘what works’.
Turning choice into clarity
The shift isn’t about restricting creativity. It’s about offering colour ranges developed specifically to suit modern architecture, contemporary interiors and long-term durability. When installers can confidently recommend a refined set of finishes, conversations move away from endless comparisons and towards outcomes: how a home will feel, how light will flow, and how different elements will work together.
Curated finishes are designed to complement one another and sit comfortably across a wide range of architectural styles, helping to avoid combinations that feel disjointed or short-lived. For installers, this means greater certainty at the point of specification, fewer last-minute changes, and a smoother pathway from decision to installation.
Why aluminium fits the brief
Aluminium naturally lends itself to curated colour palettes. Slim sightlines, strength and durability make it ideally suited to modern renovation and extension projects, where sleek lines and light-filled spaces are key. When paired with a considered colour palette, aluminium frames become part of the architecture rather than an afterthought.
This is where premium finishes come into their own. Subtle tones and high-quality coatings allow windows to complement both internal and external materials, whether that’s timber, stone or modern cladding. The result is a home that feels balanced and considered, and not over-designed.
Selling smarter, not harder
For installers, curated colour ranges also change the sales dynamic. Instead of asking customers to make decisions based on swatches alone, conversations can be framed around proven combinations and real-world applications. That builds trust and positions the installer as a guide rather than a salesperson.
There’s a commercial benefit, too. Finishes designed to perform over time reduce the likelihood of callbacks, complaints or dissatisfaction years down the line. When colour is treated as an integral part of product performance, long-term value becomes easier to communicate.
A considered approach
This thinking is central to product development here at Silka. Rather than offering colour for colour’s sake, we focus on aluminium windows and doors with finishes that are selected to enhance modern homes and support confident specification. The emphasis is on quality, consistency and design-led choice, giving installers tools that work in real sales environments.
As homeowners continue to prioritise thoughtful design, curated colour palettes are proving to be more than a trend. They are a practical response to how people buy today – helping installers simplify decisions, reduce uncertainty and deliver results that look as good years later as they do on installation day.
For many, that confidence now starts with colour.
