This study aimed to develop natural dyes for wood material that are harmless to humans and the environment. For this purpose, a tea stain and polyurethane single- and double-component water based varnish were applied by brush on the wood surfaces of pine (Pinus sylvestris L.), beech (Fagus orientalis L.), fir (Abies), and poplar (Populus sp. L.). The color change (i.e., Delta L, Delta a, Delta b) and total color change (Delta E) of the samples was determined based on the ISO 2470 standard. According to experimental results, the highest color brightness change (Delta l: -52.49) was seen in pine wood with tea dye, the highest red color change (Delta a: 11.50) was seen in pine wood with tea dye+water-based varnish, and the highest yellow color change (Delta b: 97.19) was seen in fir wood with tea dye+borax. The highest value of total color change (Delta E: 99.512) addition of borax fir wood in tea dye is obtained. Developed tea extract to waste paint, furniture processing industry has the aesthetic appearance of surface processes can be used.
