This thesis deals with assessment of roughness and color of pine wood after aging 6 and 12 months. Roughness and color were evaluated on the sapwood and heartwood. The influence of part wood, aging time and direction of wood fibers on the roughness was mo-nitored. The impact of part wood and aging time on color deviation was monitored. The roughness was evaluated on the basis of the following parameters: average rou-ghness value (Ra), mean roughness (Rq), greatest height of profile (Rz), peak height (Rp), roughness depth (Rp) and medium distance of grooves (Rsm). Most of the parameters such as a part of wood, direction of wood fibers and aging wood were statistically significant. The color deviation ΔE was determined by measuring the color of the wood surface before aging and after the 6th and 12th ages of aging. The color was measured in the CIE L*, a*, b*. The influence of the wood part and the lengths of the weahering on the color deviation were statistically significant. The sapwood and heartwood after the 6th and 12 th months reached a different color from the original. After 12 months, the difference between the color deviation of normal and core parts of wood was not statistically signi-ficant. The surface of pine wood after the 6th and 12th months of weathering reached a decrease in brightness and gray coloration. Increasing roughness and a difference color on the surface of pine wood after weathering probably caused the adsorption of impurities in the air, the leaching of oxidized lignins by precipitation water and, in particular, the influ-ence of the solar radiation that caused photochemical reactions in wood components.
