A letterbox stands out, even when you do not intend it to. The colour determines whether it blends quietly into the facade or becomes a deliberate accent. You choose from over 2000 RAL colours, which turns the letterbox into a considered part of your facade instead of a standard element.
RAL is an international colour system that lets you define a shade unambiguously. You do not say 'roughly anthracite', but a specific RAL code. That is useful when you want to match the letterbox to your facade, your front door or your joinery. The letterboxes shown on this page are supplied in over 2000 RAL colours, so you are not tied to a limited standard palette.
Choosing a letterbox colour is more than an aesthetic choice. It determines how the volume reads on the facade: as a quiet detail or as a clear accent. On a sleek, minimalist facade, a shade that stays close to the facade often works most calmly. If you want an accent instead, you deliberately choose contrast.
Start with the dominant colour of your facade. With brick in warm tones, earthy, nuanced colours often work well, while a cooler facade tends to call for a cooler shade. Also look at your front door and your windows: a letterbox that follows the same family generally looks calmer than a colour that stands apart from it.
Black letterboxes are a popular option because they combine widely and give a sleek, timeless look. A design letterbox in a dark shade is less likely to fade into the background and can emphasise a deliberate architectural line. If you want the opposite, choose a shade that visually blends into the wall.
Unsure between two shades? Then request a colour sample or view the colour on site, in natural light. Colours read differently in the morning, under cloud cover or in the evening. A letterbox that hangs on the facade all day deserves that consideration.
Colour never stands alone from material and finish. The letterboxes are made of aluminium, which provides a sleek and durable base on which the chosen RAL colour comes into its own. The finish affects how the light falls on the letterbox and therefore how the colour is experienced.
Also consider use. If you have a model with a parcel compartment or combination lock, the colour remains the first thing that stands out, but convenience determines daily contact. If you choose a colour purely for its look, a model with extra functions can fit just as well, as long as the shade matches your facade.
For practical questions about placement and regulations, such as the position of the letterbox relative to the public road, we refer to bpost or a recognised sales point. They can help you concretely with the applicable guidelines at your location.
