Gum arabic is the binder in which the pigments are dispersed to make the watercolor paints, so its use in the course of making a painting is akin to using an oil painting medium containing linseed oil with oil paints. Adding gum arabic to paints will have several effects: It will slightly extend the drying time of the paint, it will make the colors seem more vibrant and transparent, and it will increase the gloss of the dried painting.
It is also used in traditional art i.e indian miniature , islamicart and Persian miniature as well
