| Abstract | This study aimed to find the alternative choice which is apart from artificial color in creating artwork by comparing the colors of plants extracted by the different solvents and durability of colors from plants on various types of water colored paper between 200 gsm and 300 gsm. The plants were divided into three groups of the providing colors including red from roselle (Hibiscus sabdariffa L.) and sappan (Caesalpinia sappan L.), yellow from Coscinium fenestratum (Goetgh.) Colebr and the fruit of gardenia (Gardenia jasminoides J.Ellis) as well as blue from butterfly pea (Clitoria ternatea L.) and hom (Strobilanthes cusia (Nees) Kuntze) by the process of extraction with the solvents between water (H2O) and ethanol (C2H5OH) in ratio of 1:5 (plant: solvent). Then, painting these on two different type of paper is in order to comparing the durability of color including hue, saturation, and brightness by using the digital image colorimeter (DIC) in measuring the color value. The result revealed that the sappan provided the finest saturation and brightness on 300-gsm water colored paper in red group. Besides, the sappan extracted by water provides the finest saturation on the same type of paper. For yellow group, the gardenia fruit in ethanol solvent provide the finest saturation and brightness on 300-gsm water paper. Additionally, Coscinium fenestratum extracted by water (H2O) and ethanol (C2H5OH) provides the finest hue in equal on 200-gsm water paper. Lastly in blue group, butterfly pea in ethanol solvent provides the finest hue and brightness on 200-gsm water paper as well as hom provides the finest saturation on the in common paper. Finally, this study offers a method for selecting plants that provide accurate colors, and guide the process of color extraction for art that are suitable for future developments in painting materials. |
