Watercolor painting techniques involve various methods to manipulate water and pigment on paper. One common technique is wet-on-wet, where wet paint is applied to wet paper, allowing colors to blend and create soft edges. Another technique is dry brush, which uses a dry brush to apply paint, resulting in a textured, detailed effect. Additionally, glazing is a technique where transparent layers of color are applied over dried paint, enhancing depth and richness. Lifting is another method, where a damp brush or sponge is used to remove paint, creating highlights or correcting mistakes. Each technique offers unique effects and possibilities in watercolor art.
