    Natural pigments extracted from plants are raised as a vital substitute to artificial dyes. This study aimed to develop and evaluate the onion skin as dyestuff and tamarind seed coat as mordant applied in textile material. Specifically, it aimed to determine the color value of the dyed textile material in terms of boiling time (30 minutes and 60 minutes and 60 minutes and 30 minutes); to evaluate the colorfastness properties dyed textile materials in terms of washing and sunlight; determine whether there is a significant difference in the dye produced in the onion skin in terms of boiling time (30 minutes and 60 minutes and 60 minutes and 30 minutes). The study used descriptive- evaluative research design. The statistical tool used was the weighted mean. For the colorfastness properties, a questionnaire was used. Also, mobile application (color analysis pro) was used to determine the color value of the dyed poplin fabric with onion skin crude dye and tamarin seed coat powder and coffer sulfate as mordant. Color value of dyed poplin fabric yielded light shade of shadow in a group of orange and brown color when extracted 30 minutes and 60 minutes boiling time. The evaluation of the colorfastness to washing is slightly change/ good performance with the extraction and dyeing time of 60 minutes and 30 minutes with an average mean rating of 3.72 and the 30 minutes and 60 minutes extraction and dyeing accumulated an average mean rating of 4.15 showing slight change/ good performance. Tamarind seed coat and onion skin as dye had a great performance for dyeing and fixing agent. There is significant difference existed from fastness to sunlight of the natural dye in terms of mordant used and boiling time and no significant difference existed from the fastness to sunlight of the natural dye in terms of mordant used in boiling time.
