For most UK homes, the best bifold door colours are anthracite grey (RAL 7016), black (RAL 9005) and white (RAL 9016). Anthracite grey is the safest all-rounder, because it sits comfortably against red brick, render and stone and hides everyday dust well. Black gives the sharpest, most contemporary frame line. White keeps a room as bright as possible and suits traditional homes and white windows.
The best colour for your home, though, depends on four things. These are your brickwork, the colour of your existing windows, which way the doors face, and the room they open from. If you cannot settle on one colour, a dual colour frame solves most dilemmas, with one shade outside and a different one inside. The aluminium bifold doors we supply from Origin and Smarts are powder coated and come in more than 150 RAL colours, so you are rarely limited by the product. This guide explains how we at Bifold Shop help homeowners narrow that choice down.
Anthracite grey is one of the three colours we fit most often. It is dark enough to look modern but softer than black, so it works on almost any elevation, from 1970s brick to new render. It is also the colour most of our aluminium veranda customers choose. That matters if you plan to add a covered seating area outside the doors later, because the two will match. We’ve found it is the colour people are least likely to regret, because it suits a modern extension and a more traditional house equally well.
Black frames make the glass look larger and give a crisp, architectural outline. They pair especially well with slim systems and with steel-look styles such as the Soho variant of the Origin OB36+ bifold. One project we completed in Oxford used two sets of three-pane Smarts Visofold 1000 bifolds and an aluminium window, all in matt black with matching profiles. The result gave a new open-plan extension a clean, consistent look. The trade-off is that black shows pollen, dust and water marks more readily than mid-greys, so it suits homeowners who don’t mind wiping the frames down more often.
White is often overlooked, but it remains the right answer in many homes. It suits cottages, traditional houses and any property where the other windows are white. Inside, white frames reflect light back into the room rather than absorbing it. From working with clients in narrow terraced houses, we’ve found that white frames make a rear room feel noticeably bigger than a dark frame of the same size.
Beyond the big three, shades worth considering include lighter greys such as quartz grey (RAL 7039) and agate grey (RAL 7038), and black grey (RAL 7021) if you want something almost as dark as black but a little softer. Heritage greens and creams can also suit period homes and country properties. Softer greys are a good compromise if anthracite feels too dark against pale stone or in a small garden. Stronger colours can look superb, but we recommend seeing a sample in daylight first, because a bold shade chosen from a screen can look very different against real brick.
A dual colour frame gives you one colour on the outside face of the door and another on the inside. It is usually the best solution when the outside of the house and the room inside need different things.
In our experience, a dual colour frame with anthracite grey outside and white inside works better than a single dark colour for kitchen extensions and north-facing rooms. That’s because the white inner face reflects daylight back into the room, while the grey outside still matches modern windows and brickwork. A wall of dark frames on the inside of a large opening can make a room feel smaller, especially in winter when the doors stay closed for months at a time.
Dual colour also helps when you are matching different things on each side. Your outside frames might need to match anthracite windows, while the inside needs to sit with white kitchen units or oak flooring. With dual colour you don’t have to compromise on either.
We ask every customer the same questions when choosing a colour, and they are worth working through before you visit a showroom.
Colour matching is where most mismatches happen, especially when a project is spread across different suppliers. If your extension also has a roof lantern, new windows or a veranda, it is worth specifying everything in the same RAL colour from the start.
Origin makes aluminium windows as well as bifolds, so the OW-70 and OW-80 can be finished in exactly the same RAL colour as your Origin doors. Korniche roof lanterns come in stock white, anthracite grey and black, with dual colour at no extra cost, which lines up neatly with the three most popular bifold colours.
If you are fitting uPVC windows alongside aluminium doors, a close colour match is still possible. The Residence Collection comes in a range of heritage colours, including a Cotswold Collection that suits stone-built homes. We advise checking samples side by side, because powder coated aluminium and foiled uPVC can read slightly differently in daylight.
Colour is only part of the look. Frames can be finished in matt, satin or gloss. Matt suits contemporary homes and hides fingerprints well. Gloss reflects more light but shows marks more easily, and satin sits between the two.
Handles and hinges can match the frame or contrast with it. A black handle on an anthracite frame looks tidy and understated, while a brushed or satin handle on a black frame adds a subtle highlight. The Origin OB36+ uses the Knurled handle, which is available in six finishes. It is worth choosing your handle at the same time as the frame colour rather than as an afterthought.
Colour has less effect on price than most people expect. With Origin bifold doors, standard colours can be manufactured from 24 hours, while special RAL colours take around three weeks. If you have a fixed installation date, that difference matters more than any change in cost. Dual colour and less common finishes can add to the price, and we include this in your quote after survey.
For maintenance, all powder coated aluminium frames need the same simple care. That means a wipe with warm soapy water and keeping the tracks and drainage clear. Darker colours show dust and water spots sooner, and lighter colours show grime from gardens and patios.
If your home is listed or in a conservation area, the colour of your doors may matter to your local council as well as to you. The Planning Portal advises checking with your local planning authority before changing doors and windows in listed buildings and designated areas. Some councils have preferred colours for visible elevations. Rear elevations hidden from public view are usually treated more flexibly, but it is always worth checking first. Our surveyors check planning and conservation status during the survey, so colour issues are picked up before you order.
There is no single best bifold door colour. Anthracite grey is the most versatile, black gives the strongest modern look, and white keeps rooms bright and suits traditional homes. Dual colour frames let you have the right shade inside and out. The most important step is seeing real samples against your own brickwork and in your own light before you decide.
We have been helping homeowners choose, supply and fit bifold doors for over 20 years. We now work with more than 850 households every year and complete 25 to 30 installations a week with our own fitting teams.
