This animal paintings is used a water-color as a material. Water-color is a painting method in which the paints are made of pigments suspended in a water-soluble vehicle. The term "watercolor" refers to both the medium and the resulting artwork.Watercolor painting has the reputation of being quite demanding; it is more accurate to say that watercolor techniques are unique to watercolor.
Unlike oil or acrylic painting, where the paints essentially stay where they are put and dry more or less in the form they are applied, water is an active and complex partner in the watercolor painting process, changing both the absorbency and shape of the paper when it is wet and the outlines and appearance of the paint as it dries. The difficulty in watercolor painting is almost entirely in learning how to anticipate and leverage the behavior of water, rather than attempting to control or dominate it.
