There is a common misconception that 'visual contrast' is a generic term and can be achieved through the use of bold colours.
To comply with UK regulations, a mathmatical calculation must be completed to achieve appropriate contrast levels between specific surfaces.
The tool below makes this easy- and enables clever solutions that are attractive as well as compliant.

LRV- 'Light Reflectance Value'
LRV is a measurement of the quantity of light reflected from a surface, expressed as a percentage from 0-100%
WIthin the UK, LRV values must be calculated to ensure compliance with buildings regulations.
For further information please see Approved Documents M, K & T and BS 8300-2:2018.
Not necessarily, visual contrast is achieved by having appropriate LRV contrast levels, which is different from hue (colour). Whilst many designers do use vivid colours, this can result in a scheme looking institutional or eroding the design intent.
It is entirely possible to achieve a scheme which is both attractive and compliant.
This is an often overlooked area of accessible design. Having appropriate visual contrast enables a variety of users to independently navigate a space.
Users who benefit from an LRV compliant interior include:
- The visually impaired
- The elderly
- People with Dementia, or other cognitive impairments
- People with neurodiversities
- Anyone, in a low light or emergency situation
Let's get the ball rolling...
