In spite of the high number of wooden defects in wood colouring processes, the most negative colour effects for wooden material are given by knots, cracks and rots in the furniture industry. The colour effects of defective material to colouring with applying aniline, chemical (tannin (C14H10O9) + potassium bi-chromate (K2Cr2O7)) and eco-color stains (special mixture water and cellulosic thinner soluble aniline stain) to the surfaces of samples of knotted, cracked, and rotted Eastern beech (Fagus orientalis L.), oak (Quercus petreae L.) and scotch pine (Pinus silvestris L.), which are commonly used trees in the carpentry and furniture industry of Turkey, are investigated according to ASTM-D 2244. According to the results of the research, the highest metric chroma value was obtained in the samples of cracked scotch pine, which was coloured with aniline stain while the lowest metric chroma was obtained in the samples of white rotted oak and scotch pine, which were coloured with chemical stain.
