White Paper: Hunter L, a, b Versus CIE 1976 L*a*b*
Hunter L, a, b and CIE 1976 L*a*b* (CIELAB) are both color scales based on the Opponent-Colors Theory, which assumes that the receptors in the human eye perceive color as the following pairs of opposites:
- Light-dark
- Red-green
- Yellow-blue
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.
