Watercolor (American English) or watercolour (British English; see spelling differences), also aquarelle (akwaʁɛl; from Italian diminutive of Latin aqua "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. Aquarelles painted with water-soluble colored ink instead of modern water colors are called aquarellum atramento (Latin for "aquarelle made with ink") by experts. However, this term has now tended to pass out of use.
The conventional and most common support — material to which the paint is applied—for watercolor paintings is watercolor paper. Other supports or substrates include stone, ivory, silk, reed, papyrus, bark papers, plastics, vellum, leather, fabric, wood, and watercolor canvas (coated with a gesso that is specially formulated for use with watercolors). Watercolor paper is often made entirely or partially with cotton. This gives the surface the appropriate texture and minimizes distortion when wet. Watercolor papers are usually cold-pressed papers that provide better texture and appearance with a weight at least 300 gsm. Under 300 gsm is commonly not recommended for anything but sketching. Transparency is the main characteristic of watercolors. Watercolors can also be made opaque by adding Chinese white. This is not a method to be used in "true watercolor" (traditional).
Watercolor paint is an ancient form of painting, if not the most ancient form of art itself. 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, often using inkstick or other pigments. India, Ethiopia and other countries have long watercolor painting traditions as well.
Many Western artists, especially in the early 19th century, used watercolor primarily as a sketching tool in preparation for the "finished" work in oil or engraving.

Painting is the practice of applying paint, pigment, color or other medium to a solid surface (called the "matrix" or "support"). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. In art, the term "painting" describes both the act and the result of the action (the final work is called "a painting").
Gouache (ɡuˈA:ʃ,_ɡwA:ʃ; ɡwaʃ), body color, or opaque watercolor is a water-medium paint consisting of natural pigment, water, a binding agent (usually gum arabic or dextrin), and sometimes additional inert material. Gouache is designed to be opaque. Gouache has a long history, having been used for at least twelve centuries. It is used most consistently by commercial artists for posters, illustrations, comics, and other design work. Gouache is similar to watercolor in that it can be rewetted and dried to a matte finish, and the paint can become infused into its paper support.
Landscape painting, also known as landscape art, is the depiction of natural scenery such as mountains, valleys, trees, rivers, and forests, especially where the main subject is a wide view—with its elements arranged into a coherent composition. In other works, landscape backgrounds for figures can still form an important part of the work. Sky is almost always included in the view, and weather is often an element of the composition.
