Ink washes are a painting technique that involves diluting ink with water to create varying shades of gray or color. Artists apply the ink with brushes or other tools, allowing for smooth transitions between light and dark areas. This method is often used in Chinese ink painting and Japanese sumi-e, where the fluidity of the ink enhances the overall composition. The technique can be used for both fine details and broad areas, making it versatile for different styles. Ink washes are popular in illustration, calligraphy, and landscape painting, as they can evoke mood and depth through their soft, flowing appearance.
