It offers a range of techniques for textures, gradients, and color blends, allowing artists to capture light and atmosphere with spontaneity and immediacy. Essential materials include watercolor paper, brushes, paints, and a palette. Basic techniques like wet-on-wet, wet-on-dry, and glazing form the foundation for creating various effects.
