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. The traditional and most common supportfor watercolor paintings is paper; other supports include papyrus, bark papers, plastics, vellum or leather, fabric, wood, and canvas. Watercolors are usually transparent, and appear luminous because the pigments are laid down in a relatively pure form with few types of filler obscuring the pigment colors.
Watercolor painting has the reputation of being quite demanding; it is more accurate to say that watercolor techniques are unique to watercolor. 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. This is a complex process whih requires professional help to learn the essential intricate techniques involved in the art of water color painting.
Beginners must keep some difficulties within water colors that occur because watercolor paints do not have high hiding power, so previous efforts cannot simply be painted over; and the paper support is both absorbent and delicate, so the paints cannot simply be scraped off, like oil paint from a canvas, but must be laboriously (and often only partially) lifted by rewetting and blotting. This often induces in student painters a pronounced and inhibiting anxiety about making an irreversible mistake but one can overcome this with practice
