In architecture, Light Reflectance Value (LRV) is a measure of the percentage of visible and usable light that is reflected from a surface when illuminated by a light source. The LRV can be linked to a number of decisions on which a colour can be chosen. The approximate LRV of a colour indicates the amount of visible light that a colour will reflect. Black has a light reflectance value of 0% and absorbs all light. White has a light reflectance value of 100% and keeps a building light and cool. LRV also links to the use of electricity where lighter colours need less lighting, which is a direct saving for the environment. All Forbo floor coverings carry a light reflection value, which can be found in the text next to the enlargement of the tabletop and in the NCS & LRV values document.
NCS colour coding describes the colour of any material. With numeric colour codes, so called NCS Notations, such as NCS S 1080-Y70R, any colour can be described precisely. NCS has defined 1950 standardised colours at every 10th step of the colour space to represent the entire colour space. Each notation's colour sample is visually identical to any other colour sample of the same notation, whether it is a standardised colour or a colour in between the 1950 standard colours. This way you can find matching flooring colours with other coloured items in a room.
The 'Natural Colour System' NCS has been developed in order to identify the colour value, its intensity and hue for a product. By using the NCS measurement system, colours and colour groups can be identified and matched regardless of the material that has been used. In this way colour coordinates for different aspects of the interior of a building can be determined. All Forbo Flooring products carry an NCS code, which can be found next to the enlargement of the tabletop and in our download center.
