The color change of ash wood(Fraxinus mandshurica)before and after high temperature heat treatment were investigated with WSC-S color difference meter in this paper.The results showed that:the color of treated wood is affected by the processing temperature,the higher the temperature,the darker the appearance,moreover,the change in L component can be used for quantitative analysis on color change.The color of treated ash wood by suitable processing temperature could be simulated to some valuable wood,for example,teak wood,some rosewood species,etc.The color of treated wood could be well replicated from laboratory scale experiments to commercial scale production.
