Watercolor paintings for sale online from artist. Watercolor is the most unforgiving medium of all of the arts. It is the most technique driven and procedural driven form of art on paper. It can be expressive and experimental, but most of the time, one chance is all you get. The color white has to come from the paper, you can only make a dark area glider by washing but you can never make it white again. Light areas are painted once. Watercolor by their very nature are fragile, can be damaged by moisture and require love and care by the owner. Art is governed by its limitations and those limitations are often the street of the medium. Doing it once and taking what you get at first is refreshing, exciting, risky and worth it.
