A wash is a term for a visual arts technique resulting in a semi-transparent layer of colour. A wash of diluted ink or watercolor paint applied in combination with drawing is called pen and wash, wash drawing, or ink and wash. Normally only one or two colours of wash are used; if more colours are used the result is likely to be classified as a full watercolor painting.

Watercolor or watercolour, also aquarelle, 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 by experts. However, this term has now tended to pass out of use.
