also aquarelle from French, is a painting method. A watercolour is the medium or the resulting artwork, in which the paints are made of pigments suspended in a water soluble vehicle .Watercolour painting has the reputation of being quite demanding. 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 watercolour 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 watercolour painting is almost entirely in learning how to anticipate and leverage the behavior of water, rather than attempt-ing to control or dominate it. (source:
