Watercolor (American English) or watercolour (British English; see spelling differences), also aquarelle (French, from Italian diminutive of Latin aqua "water"),^[1] 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 been more and more passing out of use.^[2][3]
