LRV Values

To help you meet the duties of the Disability Discrimination Act (DDA), guidance in Building Regulations Part M recommends that adjacent critical surfaces (i.e. ceiling/wall/door and floor) have a visual contrast of 30 LRV difference. LRV (Light Reflectance Value) is defined as the amount of light reflected by that colour, measured on a scale of 0-100. A table of all the LRVs for the Glidden Trade Exclusive (GTE), RAL and BS colour ranges are listed in the tables below.
