Color Measurement L A B . In addition to quantifying the overall color difference between a sample and standard color, delta e* was intended to be a single number metric for pass/fail tolerance decisions. It is not used as frequently today as it was in the past because the cie l*a*b* scale, which was released in 1976, has gained popularity.

The hunter l, a, b color scale evolved during the 1950s and 1960s when many scientists involved with color measurement were working on uniform color scales. L*a*b* is an international standard for color measurements, adopted by the commission internationale d’eclairage (cie) in 1976. Regardless of the which color space name you call it, it’s important to know what l*, a*, and b*stand for.

The color of foods has been measured usually in l*a*b* units using either a colorimeter or specific data acquisition and image processing systems. L*a*b* values are perceptually uniform, meaning that the degree of difference between two colors corresponds to the euclidean distance of them in the l*a*b*. The product is then summed for the wavelengths in the visible spectrum to.
