Luminance Contrast Calculator
Luminance contrast is established when you compare the measurement of light reflected from one surface, compared to the light reflected from another surface. Light Reflectance Value (LRV) is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. Once you you have the LRV of the two surfaces you want to compare you enter them below and our calculator provides the compliance answer.
