Watercolor or popularly known as aquarel is a painting medium that uses water solvent pigments with transparent properties. Although the surface medium can vary, paper is usually used. Besides that, it can also be papyrus, leather, cloth, wood or canvas.
In general, watercolor is used because of its transparency. Gouache is a water thinning medium that is not transparent but is closed.
Watercolor paintings are usually very expressive, or vice versa, very impressive, depending on the technique used.
Watercolor is used with a pointed brush and other brush shapes that are soft-bristled and use excess water, but can also be mixed with other materials. Usually acrylic paint. Watercolor with excess water mixture produces bright and fresh colors. This color is produced by light that is able to penetrate the transparent layer of paint.
White is usually produced from parts that are not given a coat of paint. Very rare paintings that deliberately give a white layer of watercolor.
Using color paint requires high patience. Commonly used techniques are usually produced from layers that are overlapped after the previous layer has dried to produce the desired color gradation. But another wet-on-wet technique that imposes color on a wet layer also requires high accuracy to get maximum results. The bad risk is the paper becomes curved or torn if too much water is used and too much brush friction with the surface of the paper. If the paper is curled or corrugated the paper can be ironed so that the paper is flat as before.
