Summary:The authors propose two new methods for the color measurement. The first method uses the chromaticity coordinates of the "Commission Internationale de l'Eclairage" and the second one, more simple and original, allows to calculate the dominant wavelength directly from the net absorbance (A subindex 560-A subindex 720) of the honey samples. It is also proved in this paper that the color measurement using the methods of Barbier-Valin and AOAC lacks objectivity. It is also suggested in this work to measure the turbidity by means of the absorbance at 720 mm because through this value it may be determined the equivalent result in "Cloudy" degrees of the AOAC scale.
