Dyeing from natural sources is gaining increasing interest due to its outstanding merits of being environmentally friendly. Assam tea leaves are natural products and are easy to use. The oxidation process is a chemical reaction that leaves turn color from green to brown. The characteristic of color is used for product dyeing. The research is divided into 3 sections. In Section 1, the comparison of color value between the dyeing woods from Assam tea leaves and teak color which measurss the difference of color space by the CIE Lab system. Section 2, the dyeing wood from Assam tea leaves is coated by sanding sealer and lacquer that is compared with teak color. In the last section, find the optimal parameter for extraction of wood dyeing that includes Assam tea leaves, Sodium Hydroxide, water, boiling time, and dyeing time. The research is tested by 2k full factorial design. The results of section 1, the dyeing rubber wood from Assam tea leaves displayed light brown and dark brown depending on the extraction ratio. The color value includes the L* value is 34.16 – 54.14, the a* value is 8.74 – 15.85 and the b* value is 12.05 – 24.21. In section 2, the minimum value, maximum value, and average value of color space are 2.02, 13.90 and 4.53, respectively. In the last result, the experiment shows that boiling time’s not effect on color space is statistically significant. The experiment was determined by Assam tea leaves, 40 grams, Sodium Hydroxide, 10 grams, water, 400 milliliters, and dyeing time, 4 times that are the least differential value at 1.47. The general observer is unable to determine the difference in color.
