LRV Explained

What is LRV?

Light Reflectance Value is the acronym referring to the lightness and darkness of colours, running on a scale from 0% to 100% that increases with the light in a colour.

LRV is commonly confused with "intensity", which actually refers to how vivid or dull a colour is.

Why is LRV important?

LRV is vital for contractors and designers working with care homes, hospitals and other healthcare facilities used by patients suffering from colour blindness, visual impairments or dementia. Using colours that are distinct from another will help aid navigation and can improve mood.

Using clear and high level contrasting colours will help patients distinguish between walls and ceilings, seating, doors and other surfaces. The best way to measure contrast is with the LRV, with at least 30 point difference between colours on adjoining surfaces, helping meet legal requirements of the Equality Act 2010.
