Watercolor techniques involve various methods to manipulate water-based paints for artistic effects. Common techniques include wet-on-wet, where wet paint is applied to wet paper, creating soft blends, and wet-on-dry, where wet paint is applied to dry paper for sharper edges. Other techniques include glazing, which layers transparent washes for depth, and lifting, where a damp brush removes paint for highlights. Additionally, artists often use salt to create texture, as it absorbs water and leaves interesting patterns. Masking fluid can protect areas from paint, allowing for crisp white spaces. Experimenting with these techniques can enhance creativity and improve skills in watercolor painting.
