Abstract
The colour of 112 Moroccan honeys was assessed by tristimulus colorimetry based on their diffuse reflectance spectra with a white background and a black background, with the application of the equations by the non-uniform colour space CIE Y10 X10 Y10, and by the uniform colour space CIELAB proposed by the Commission Internationale de l'Eclairage (CIE). As the weighted-ordinate method (Ay = constant) establishes, the visible reflection spectra of the samples is weighted according to the characteristic factor of the selected visual reference conditions, 10° visual field observer and CIE standard illuminant D65. The results obtained by the discriminant analysis of the results revealed that the unifloral honeys studied (eucalyptus, orange, heather and mint) were better characterized when measured in the CIELAB colour space against a white background (93% correct) than using a black background (66%).
