Rezumat: The presented research pursued the colour modifications suffered by heat-treated spruce and black pine wood, when exposed to natural light, as function of time, but also as function of the heat- treatment parameters applied. To this purpose, thin 20x20x0.5mm samples were cut out from wood pieces heat-treated in an electric oven at 180ºC and 200ºC for 1, 2 and 3h. The samples were scanned right after the heat-treatment in order to establish the “initial” colour. Then, the upper half of each sample was covered with a sealer and they were exposed on the inner side of a well-lighted window and scanned again after 1 to 6 months of exposure, in order to evaluate the colour modification of the uncovered part. The results were expressed in the CIE L*a*b system. The obtained results are important with a view to valorise heat-treated spruce and pine wood panels as interior wall claddings and other wooden elements for interior design.
