In artistic terms, this describes a technique where a diluted application of paint or ink is spread across a surface. This application results in a translucent layer of color, often used to create subtle tonal variations, backgrounds, or underpaintings. For instance, an artist might use thinned watercolor to create a delicate, atmospheric sky in a landscape painting.
This method is valued for its ability to create depth and atmosphere quickly and efficiently. Historically, it has been employed across various media, including watercolor, ink, and acrylic, playing a significant role in the development of landscape painting and illustration. The technique allows for broad, expressive marks and subtle gradations of color, which are beneficial for establishing the overall mood and composition of a piece.
