木材颜色是反映木材表面视觉和心理感觉最为重要的特征.红木及一些深色名贵木材具有其独特的颜色，紫檀木类为红紫色，花梨木类、香枝木类及红酸枝木类为红褐色，黑酸枝木类为黑紫色，乌木类、条纹乌木类和鸡翅木类主要为黑色，由于其独特的漂亮的颜色，越来越倍受人们的喜爱.但随着红木及一些深色名贵木材数量的减少，人们开始采用物理(高温热处理)或化学(染色)的方法来改变木材的颜色，使其接近红木和一些深色名贵木材，从而来仿生红木及名贵木材颜色.本研究采用CIE L*a*b*法对几种红木及深色名贵木材的颜色参数值进行测定，为高温热处理改变木材颜色提供参考数据.结果表明：紫檀木类木材材色参数的色品分布特征L*为27、a*为8、b*为7；花梨木类木材材色参数的色品分布特征L*为38-54、a*为15-36、b*为22-47；香枝木类木材材色参数的色品分布特征L*为33-52、a*为15-21、b*为25-30；红酸枝木类木材材色参数的色品分布特征L*为26-66、a*为15-24、b*为21-33；黑酸枝木类木材材色参数的色品分布特征L*为16-21、a*为2-24、b*为4-14；鸡翅木类木材材色参数的色品分布特征L*为26、a*为11、b*为14；乌木类木材材色参数的色品分布特征L*为23、a*为6、b*为7；古夷苏木和红檀木材材色参数的色品分布特征L*为30-36、a*为20、b*为25-30.
