Inorganic pigments are the most preferred pigments to be produced due to their greater resistance to fade, efficiency in the application, and how it is overall easier and faster to produce. However, natural water is polluted, and close vegetation is damaged because of the affected water channels that have been damaged due to improper disposal by the manufacturing industry. This paper reviews a comparative analysis of the colorfastness of extracted pigment from kangkong with varied alcohol solutions. A total of 7 varying ethyl alcohol solutions with concentrations ranging from 10% to 70% were obtained using the dilution equation. Kangkong leaves were then utilized for the extraction of chlorophyll due to its high leaf yield rate. The Brightness levels and Saturation levels had an inverse and direct correlation to the alcohol concentration, respectively. This suggests that a greater alcohol concentration is more effective and efficient in the extraction of chlorophyll because the samples had a better expression of colors. After observing the color value before and after administering the colorfastness test, the alcohol concentration in the extraction of chlorophyll has an inverse relationship with the colorfastness of the pigment on textile material.
