Light reflection values LRV

LRV is a universal value for ‘contrast’. It measures the proportion of useful light reflected by a colored object. It represents a relative light and darkness value rather than an actual color. Therefore, dissimilar colors could have the same LRV. LRV is measured on a scale of 0 to 100, 0 being perfect absorbing black and 100 being perfect reflecting white (in reality you never find these perfect objects – a bright white would typically have a result of an LRV of 85)

LRV, light reflectance values, shown below are the results of multiple testing, however, due to the natural variation in wood there will be some deviation from these test values. LRV is shown as an average of the measurements. The variation width is the difference between the highest and the lowest measurements.
