In this study, the correlation between image of wood and its color was investigated by using 16 groups of specimens (printed, decorative veneer overlaid and various colored transparent paper overlaid 123 panels). To calculate the correlation factor between hue and image, a new numerization method of hue was proposed, which made it clear that hue of wood especially near 7.5 YR gave "warm" image, and clolor of near 10 R and 2.5 YR with a low brigthness value gave "gorgeous" image. Brightness had correlation with "ligth" and "neat and clear", and had negative correlation with "heavy and thick ", "sober"and "calm". Chroma had correlation with "showy" and negative with "sober". The influence of clear coating on image was investigated on the adjacent sliced specimens of veneer overlaid plywood (8 species) with the same figures. Clear coating gave gloss and also contrast of wood grain figure, and consequently "showy" and "gorgeous" image increased but "elegant" and "fire" image decreased. In the case of species whose brigthness value decreased by coating, "calm" image increased. Anisotropy of glossiness based on wood fiber direction was observed and the anisotropy did not disappear did not even if the specimen was clear-coated.
