Watercolor (American English) or watercolour (British English; see spelling differences), also aquarelle (French loanword), a diminutive of the Latin for water, is a painting method in which the paints are made of pigments suspended in a water-based solution. Watercolor refers to both the medium and the resulting artwork.
The traditional and most common support—material to which the paint is applied—for watercolor paintings is paper. Other supports include papyrus, bark papers, plastics, vellum, leather, fabric, wood and canvas. Watercolor paper is often made entirely or partially with cotton, which gives a good texture and minimizes distortion when wet. Watercolors are usually translucent, and appear luminous because the pigments are laid down in a pure form with few fillers obscuring the pigment colors. Watercolors can also be made opaque by adding Chinese white.
In East Asia, watercolor painting with inks is referred to as brush painting or scroll painting. In Chinese, Korean and Japanese painting it has been the dominant medium, often in monochrome black or browns. India, Ethiopia and other countries have long watercolor painting traditions as well. Fingerpainting with watercolor paints originated in mainland China.
Watercolor painting is extremely old, dating perhaps to the cave paintings of paleolithic Europe, and has been used for manuscript illustration since at least Egyptian times but especially in the European Middle Ages. However, its continuous history as an art medium begins with the Renaissance. The German Northern Renaissance artist Albrecht Dürer (1471–1528), who painted several fine botanical, wildlife, and landscape watercolors, is generally considered among the earliest exponents of watercolor. An important school of watercolor painting in Germany was led by Hans Bol (1534–1593) as part of the Dürer Renaissance.
