The algarrobo blanco (Prosopis alba) is characterized by its excellent physical35 mechanical properties in its wood. The colour is an important feature in certain use of wood, and affects its quality. The objective of this work was to evaluate the colorimetric variation between sites, section and region of the wood samples and correlate colorimetric parameters with dentrometric features of the tree. The samples were obtained from three natural stands (Los Arias, Santiago del Estero, Isla Cuba, Formosa and Villa Ángela, Cha40 co) and a plantation (San Isidro, Santiago del Estero), in the Chaqueña region of Argentina. The colorimetric parameters (L *, a *, b *) were obtained with a KONICA MINOLTA CM42 5 spectrophotometer with illuminant D65. The colorimetric analysis confirmed that there are significant differences in colorimetric parameters between sites, section and region in the wood samples analyzed. The size of the trees is directly related to the colorimetric pa45 rameters.
