You may hear people talk a lot about ‘RAL’ colours in the fenestration industry but what does it actually mean and what colours are popular? It’s a standard colour system that helps keep things consistent. Let’s take a look at what it’s about and which shades people love at the moment.
RAL is a colour management system used throughout Europe, originally created in Germany. It began as a collection of 40 colours known as ‘RAL 840’. Before this manufacturers and customers had to exchange samples to describe a tint, whereas after RAL’s were developed they could rely on a number. The RAL system provides a universally recognisable palette of colours, ensuring precision and consistency for colour selection.
The RAL colour system now comprises of over 2,500 colours all identified with a unique RAL code. Today, it stands as the most widely used Central European colour standard, applied across architecture, construction, industry, recreation, and road safety.
You can typically find the unique RAL code on the reverse side of any colour swatch. Alternatively, you can contact the product manufacturer. A RAL colour code can also be located on various websites, such RAL Colour Chart.
Over the years, as you can imagine, various RAL colours have risen and fallen in popularity as design trends change and evolve. A popular RAL colour for a kitchen might not be the same as one for an aluminium entrance door. That being said, here are some of the most popular RAL colours for windows and doors from the last few years, in no particular order.
White will always remain a popular choice for windows and doors and for obvious reasons. Its neutral, classic, complements the majority of architectural styles. White is also very easy to coordinate with other colours and styles
Grey and in particular Anthracite grey has dominated the industry for the last few years. Anthracite Grey provides a contemporary, industrial look but is also very timeless. Mostly popular with more modern buildings but it can also work in a traditional setting.
A light grey with a subtle green undertone making it a versatile choice. Agate is a perfect neutral for combining exterior materials such as render and cladding.
A striking dark grey colour that takes inspiration from the colour of volcanic rock. It’s a slightly lighter shade than Anthracite grey and is a popular choice for modern and traditional homes. Basalt Grey can be a great alternative for those who like the look of anthracite but want something a little more understated. It can add a touch of depth to a space.
In short, a RAL code offers a simple and reliable way to choose the perfect shade for your windows and doors. With popular options like Pure White, Anthracite Grey, and Agate Grey leading the way.
