Abstract

Color, whiteness and glossiness of four caesalpiniaceae wood species were characterized by quantitative measurements and image analysis, i.e., which were respectively Berlinia bracteosa Benth., Monopetalanthus heitzii Pellegr., Distemonanthus benthamianus and Erythrophleum ivorense A. Chev. The color of four wood species was evaluated to be consistent by the CIELab and CIE1931 color system. The boards of B. bracteosa, M. heitzii and E. ivorense was divided into dark color. The wood color of B. bracteosa had the highest red to green hue, while the wood appearance of D. benthamianus had the brightest and yellowest color within the four wood species. The whiteness of D. benthamianus was significantly higher than the other three wood species, namely tangential section 21.9% and radial section 22.2%. Hence, the color of the four species varied significantly, which was closely related to internal constituents of wood materials. M. heitzii wood had the highest surface glossiness on both tangential and radial section surfaces. The surface glossiness was highly related to the wood microstructure, especially with the pore and groove structure. This study of the visible characteristics provided the indicated knowledge for the application of the four wood species in wood industry.
