Light Reflectance Value (LRV) Guidance
Light Reflectance Value (LRV) measures the percentage of visible light reflected from a surface.
Measured on a scale from 0 to 100:
0 = absolute black (absorbs all light)
100 = pure white (reflects all light)
LRV is commonly used in architectural specification, accessibility compliance, and interior design to assess visual contrast between surfaces.
Understanding LRV helps architects, fabricators, and specifiers select finishes that improve visibility, usability, and inclusive design compliance.
At Alpro, we supply a wide range of finishes suitable for projects where visual contrast and compliance are important considerations.
LRV is particularly important in:
Inclusive building design
Approved Document M compliance
Visual contrast requirements
Commercial and public buildings
Healthcare and education environments
A suitable contrast in LRV between adjacent surfaces can improve visibility for visually impaired users and assist with safer navigation throughout a building.
| LRV Range | Appearance | Typical Use |
| 0–10 | Very Dark | Black finishes, low-reflective surfaces |
| 11–35 | Dark | Bronze, dark grey, anthracite |
| 36–55 | Mid Tone | Neutral metallics, medium greys |
| 56–75 | Light | Satin aluminium, pale finishes |
| 76–100 | Very Light | White and highly reflective finishes |
Many accessibility standards recommend a minimum LRV difference of 30 points between adjacent surfaces to achieve effective visual contrast.
Always refer to the latest project specifications and applicable building regulations.
