What is LRV?
Understanding LRV in Ironmongery: Why It Matters in Interior Design.
At Excelsior Panelling Systems, we believe that great design is about more than just aesthetics — it’s about creating spaces that are functional, compliant, and inclusive for all users. Light Reflectance Value (LRV) often goes unnoticed yet plays a vital role in accessibility and visual harmony, particularly when it comes to ironmongery and interior fittings.
What Is LRV?
Light Reflectance Value (LRV) measures the amount of visible light that a surface reflects when illuminated by a light source. It’s expressed as a percentage on a scale from 0 to 100, where 0 represents absolute black (no light reflected) and 100 represents pure white (maximum light reflected).
In practical terms, LRV tells us how light or dark a colour will appear — and how it will affect the brightness and perception of a space. For instance, a dark walnut panel might have an LRV of around 15, while a light maple could be closer to 60. This simple value helps designers predict how materials will interact with both natural and artificial light.
Why LRV Matters in Design
LRV has both aesthetic and functional importance. A balanced mix of light and dark surfaces can enhance depth and contrast within a room, influence mood, and even impact energy efficiency by affecting how much light is absorbed or reflected.
LRV and Accessibility Compliance
LRV becomes particularly important when considering visual contrast — ensuring that adjacent surfaces, such as doors, walls, and ironmongery, are distinguishable from one another. Without sufficient contrast, key features like door handles and push plates can blend into their backgrounds, creating difficulties for people with visual impairments.
Accessibility standards such as BS 8300 and Building Regulations Approved Document Part M emphasise the need for appropriate visual contrast between critical building elements. These guidelines are designed to make public and commercial spaces easier to navigate for all users, including those with limited sight.
A common recommendation is to achieve a difference of at least 30 points in LRV between adjacent surfaces. For example:
- A dark door (LRV 20) would need ironmongery with an LRV of 50 or higher to meet the contrast requirement.
- Conversely, a light door (LRV 70) would need darker ironmongery (LRV 40 or below) to provide sufficient distinction.
By ensuring the right contrast levels, designers can meet accessibility standards while enhancing the usability and safety of a space.
LRV in Ironmongery
Ironmongery — including door handles, hinges, locks, and push plates — plays a key role in the overall usability and appearance of interior spaces. The finish and material of these components have a direct impact on their LRV values.
For example:
- Polished stainless steel tends to have a higher LRV due to its reflective surface.
- Brushed or satin finishes reflect less light, lowering the LRV.
- Matte black, bronze, or antique finishes usually have low LRVs, creating strong contrast against light doors or panels.
The right choice depends on both design intent and compliance requirements. In many cases, achieving contrast doesn’t mean compromising style — modern hardware finishes can deliver both visual clarity and aesthetic cohesion.

How Excelsior Ensures LRV Compliance
At Excelsior Panelling Systems, we work closely with architects, designers, and contractors to ensure that every project meets not only the highest aesthetic standards but also essential regulatory requirements. When specifying wall panelling, doors, and associated ironmongery, we can advise on the ideal LRV combinations to achieve the necessary contrast and compliance.
Our bespoke manufacturing process means we can precisely colour-match or contrast finishes across materials — ensuring that every element, from wall panels to door hardware, contributes to a unified and accessible design.
Understanding and applying LRV principles within interior design isn’t just a technical requirement — it’s an opportunity to make spaces safer, more inclusive, and visually balanced. By carefully considering the relationship between finishes, tones, and materials, designers can create interiors that look exceptional and perform to the highest standards.
