Importance of luminance contrast

Guardian’s Non Slip Stair Nosing incorporates luminance (reflection of light) contrast in all settings, which is an essential aid to people with vision impairment. This is due to the fact that it enhances sight far better than colour contrast (the perceived difference in a colour that occurs when it is surrounded by another colour).

Luminance contrast is preferred to colour contrast as it highlights the difference in the light/dark qualities of two adjoining surfaces rather than just their colours. This means that it offers light /dark differences that can be picked up easier by people who are vision impaired.
