Hunter L, a, b Versus CIE 1976 L*a*b*

Both the Hunter L, a, b scale and the CIE 1976 L*a*b* (CIELAB) scale are visually meaningful; the three values can be easily understood and translated into color. They are, however, calculated differently. The formulas for Hunter L, a, and b are square roots using CIE XYZ, whereas CIELAB is calculated using cube roots of XYZ. Submitted by HunterLab
