- Abstract
The homogeneity of wood color in a batch to be marketed is of fundamental importance, as it will reflect in products quality resulting from its processing. In this context, this study aimed to evaluate, through colorimetric technique, the colorimetric parameters of Eucalyptus spp. wood from 25 clones and classify them into groups, according to color similarity degree. It was determined the lightness (L*), red-green color coordinate (a*), yellow-blue chromatic coordinate (b*), chromaticity (C*) and ink angle (h). Radial and tangential faces and three positions in the radial direction were characterized using a colorimeter. Comparing to tangential planes, the results showed that radial plane presented larger values of L* and h in wood near the bark. Furthermore, it was observed higher values of L* in samples from intermediate radial positions. Finally, it was found that, as radial growth ocurred, developed timber showed less intense yellow shades. The definition of the wood color tones will be useful in timber market in the homogenization of their products, which will facilitate their marketing.
