Light Reflectance Value Contrast
As an industry ‘rule of thumb’, a 70% Light Reflectance Value (LRV) contrast between sign text and background colors is an ideal guideline to follow when evaluating color and finish options. LRV values for all paint finishes in our Standard Ranges and the calculation used to calculate LRV contrast have been provided for you in our Standard Color Documentation. Most major paint manufacturers include LRV values for their colors in their swatch books. These values, along with ours, can be used in the manual calculation below.
