A "brush wash" is a technique used in painting and art to create a soft, even layer of color. This method involves using a brush to apply a thin wash of paint, often diluted with water or a medium, over a surface. The result is a translucent effect that can enhance the depth and richness of the artwork. Brush washes are commonly used in various art forms, including watercolor painting and acrylic painting. Artists often use this technique to establish backgrounds or to create subtle gradients. It allows for blending colors smoothly, making it a popular choice for both beginners and experienced artists.
