The development of watercolors from Annatto seeds for using in the creation of artworks

Abstract

This article regarding the development of watercolors from Annatto seeds for using in the creation of artworks aims to 1. develop the watercolors from Annatto seeds for using in the creation of artworks and 2. compare the color values from Annatto seeds with the 3 formulas from the research. These are including the first formula from the mixture of Annatto powder, water, as well as ethanol, the second formula from the mixture of Annatto powder, water, Arabic gum, as well as honey, and third formula from the mixture of Annatto powder, water, glycerin, Arabic gum, as well as honey. Then, painting all formulas with different collecting time (immediate, 3-day, and 7-day collection) on the different types of paper and measuring by colorimeter with
L a* b* color value. It is found that the mixture of the first formula on 300-gram paper performs +a value in
red zone with the highest level at 37.2 and shows the high saturation in red zone. In contrast, the mixture of second formula on 200-gram paper perform +a value in red zone with the lowest level at 15.10. For the highest L value, the second formula with 7-day collection performs on 200-gram paper at 81.00 and 300-gram paper at 80.10.     For the lowest reduction of +a value, the third formula from the mixture of Annatto powder, water, glycerin, Arabic gum, as well as honey performs on 200-gram paper with the differences at 9.10 and 300-gram paper at 9.30. Meanwhile, the highest reduction of +a value in red zone belongs to the second formula from the mixture of Annatto powder, water, Arabic gum, as well as honey. This performs on 200-gram paper with the differences at 17.90 and 300-gram paper at 11.70. For the lowest L value (shadiness) of color, the third formula with 7-day collection performs on 300-gram paper at 11.00. Thus, the mixtures with glycerin provide the +a value in red zone and the lowest L value. Besides, the measurement of color from the first formula with 7-day collection painted on the paper provides the highest + b value in yellow zone at 42.70.
