The color of 97 species of wood specimens from French Guiana was measured o
n their radial and tangential surfaces with a colorimeter. We obtained the
tristimulus values of X, Y, and Z of the 10 degrees 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 negati
ve correlations against L*. These results imply that wood color should be d
iscussed by separating wood specimens into the high-and low-lightness group
s. A good positive correlation was found between the L* and h throughout th
e 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 rela
tion with L*.
