The objective of this study was to investigate the effect of temperature on the changes in color and weight of jabon (Anthocephalus cadamba) wood heat-treated in oil and air. Each heat treatment was performed using temperatures of 170, 190, and 210°C for 4 h. The CIE-Lab color system was used to determine the color change of heat-treated woods. The change in weight before and after heat treatment was also investigated. The weight of the wood after oil heat treatment increased yet decreased in the wood treated with air heat treatment. Samples treated with oil heat showed a greater decrease in brightness (L*) than samples treated with air heat treatment. The red/green chromaticity (a*) of the both heat-treated samples increased at 170 and 200°C and decreased at 210°C. The yellow/blue chromaticity (b*) in wood heat-treated in oil and air increased at 170°C and 190°C and decreased at 210°C. The overall color change (ΔE*) of both heat-treated samples increased as the temperature increased. As a result, it becomes clear that oil heat treatment outperformed air heat treatment in terms of enhancing the color of wood
