Coloring materials for fabric painting can be produced from natural dyes and synthetic dyes. Natural and synthetic dyes have their respective advantages and disadvantages. The combination of the two colors will give the impression of a brighter color, and slightly reduce environmental pollution. The objectives of this research are: 1) Knowing the processing of synthetic and natural dyes for fabric painting; 2) Knowing the results of applying synthetic and natural dyes to fabric painting. The method used in this research is the research and development approach model Research and Development (R&D) and data analysis. Trials in this study were carried out with dye using 4 types of cloth with the help of a validator as an assessor of the coloring results. The results of this study indicate that synthetic dyes are lighter than natural dyes. Meanwhile, the colors produced from natural dyes tend to be darker. In painting this cloth, the writer needs a combination of dark and light colors. Therefore, the use of synthetic and natural dyes requires mixing of colors. The fading test conducted by the author for the color absorption of diamond crape on the fabric is very good. Thus it can be concluded that the use of natural and synthetic dyes can be applied to fabric painting by conducting trials first to get the right color.

Rosella (Hibiscus sabdariffal L.) contains anthocyanins which can be used as natural dyes and at the same time as an antioxidant that functions as an antidote to free radicals. The aim of this research was to formulate and test the physical characteristics of the blush on cream preparation from the essence of Rosella (Hibiscus sabdariffa L.) as a natural dye. This type of research is an experiment in the laboratory. The extract of Rosella calis flower is crushed and the filtrate is taken by extracting it. The extract is made into blush on cream preparations with a concentration of 20%, 40% and 60%. The organoleptic test results of blush on cream on the control were soft textured, white, smelled like cream, soft-textured F1, ivory white, Rosella flower-like smell, soft-textured F2, light cream colored, Roselle flower-like smell, and F3 small granular texture pink color, distinctive smell of Rosella flower, homogeneity test on homogeneous control, homogeneous F1, homogeneous F2, and not homogeneous F3, control pH test values: 6, F1: 6, F2: 6, F3: 4, control spreadability test: 6 , 3 cm, F1: 5.7 cm, F2: 5 cm, F3: 4.5 cm, control adhesion test: 4.42 seconds, F1: 4.21 seconds, F2: 4.19 seconds, F3: 4.12 seconds and emulsion type test on control: M / A, F1: M / A, F2 M / A, F3: M / A. The formulation and physical characteristics test of blush cream from the extract of Rosella flower petals (Hibiscus sabdariffa L.) cannot be formulated as a blush cream preparation and does not have good characteristics, one of which is the exposure to light and heating during the formulation.
