Colorimetric measurements using CIEL * a * b * system are often carried out for the aesthetic evaluation on wooden surfaces. This study aims to characterize the colour of heartwood of twenty one tropical wood species by the CIE-L * a * b * colour system – lightness (L* ), redness (+a* ), yellowness (+b* ), chromaticity (C* ) and hue angle (h° ). Colour coordinate a* shoved a negative correlation against L* , while colour coordinate b* shoved a positive trend against L* , however both with a relatively small significance. No significance was found between the chromaticity C* and the lightness L* . Only for the hue angle h°was observed a more significant positive correlation against the lightness L*.
