Abstract

The color of 97 species of wood specimens from French Guiana was measured on their radial and tangential surfaces with a colorimeter. We obtained the tristimulus values of X, Y, and Z of the 10° standard observer under the illuminant of D 65, and the values of the CIELAB color system, L *, a*, b*, C*, and h. When the lightness index (L *) was <54, b *, C *, and h showed positive correlations against L *. When L * was >54, a * and C * showed negative correlations against L *. These results imply that wood color should be discussed by separating wood specimens into the high and low-lightness groups. A good positive correlation was found between the L * and h throughout the whole range of L *. It is thought that the value of h can be an important index, as can L *, for comparing of wood color because h shows a simple relation with L *.
