Watercolor pencils are a unique art medium that combines the features of colored pencils and watercolor paints. They have a water-soluble core, allowing artists to create vibrant colors and soft washes. When used dry, they function like regular colored pencils, providing precise lines and details. To achieve a watercolor effect, artists can apply water with a brush after drawing. This activates the pigments, blending them smoothly and creating a painterly look. Watercolor pencils are popular among artists, students, and hobbyists for their versatility and ease of use, making them suitable for various styles and techniques.
