Watercolor (American English) or watercolour (British English; see spelling differences), also aquarelle (French:[akwaʁɛl]; from Italian diminutive of Latin aqua 'water'),[1] is a painting method[2] in which the paints are made of pigments suspended in a water-based[3] 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.[4][5]
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.[6][7] This gives the surface the appropriate texture and minimizes distortion when wet.[8] Watercolor papers are usually cold-pressed papers that provide better texture and appearance with a weight at least 300 gsm (140 lb). Under 300 gsm (140 lb) is commonly not recommended for anything but sketching.[9][10] Transparency is the main characteristic of watercolors.[11] Watercolors can also be made opaque by adding Chinese white. This is not a method to be used in "true watercolor" (traditional).[12]
Watercolor paint is an ancient form of painting, if not the most ancient form of art itself.[2] In East Asia, watercolor painting[13] with inks is referred to as brush painting or scroll painting. In Chinese, Korean and Japanese painting[14] 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.[15] Until the end of the eighteenth century, traditional watercolors were known as 'tinted drawings'.[16]

^"Ancient Egyptians used water-soluble translucent paints to decorate papyrus scrolls. They used such earth pigments as ochres and siennas, as well as minerals like reds, cinnabar, blue azure, green malachite, and so on, with gum arabic and egg white. Technically, these water-soluble colors were watercolors." London (2021, p. 19)

^"It consists of a mixture of pigments, binders such as gum arabic and humectants such as glycerin, which together with other components, allow the color pigment to join and form the paint paste, which we know as watercolor. With regard to the colors, the quality of the pigments and their degree of concentration, it is what determines how good the watercolor is and also its price. A paint that has a high concentration of pigment, professional type, allows us to use it with a large amount of water without losing the intensity of color." Viscarra (2020, p. 47)
