LRV

What is LRV (Light Reflectance Value)?

Light Reflectance Value (LRV) is the total quantity of visible and useable light reflected by a surface in all directions and at all wavelengths when illuminated by a light source.

LRV is a measurement that tells you how much light a color reflects, and conversely how much it absorbs. LRV runs on a scale from 0% to 100%. Zero assumed to be an absolute black and 100% being an assumed perfectly reflective white. An absolute black or perfectly reflecting white does not exist in our everyday terms. Approximately speaking, the average blackest black has a LRV of 5% and the whitest white 85%.

Some yellows can measure up into the 80′s or 90′s as well. Although LRV can be most easily illustrated as a black-to-white scale, all colors have LRVs as well; that is, any color can be mixed into darker or lighter shades.
