Impasto is a painting technique where thick layers of paint are applied to the canvas, creating a textured surface. This method allows artists to build up the paint, making it stand out and catch the light in unique ways. The result is a dynamic, three-dimensional effect that adds depth and interest to the artwork. Many famous artists, like Vincent van Gogh, used impasto to enhance their paintings. By applying paint directly from the tube or using a palette knife, they created bold strokes and vibrant colors. This technique not only showcases the artist's brushwork but also invites viewers to experience the artwork in a tactile way.
