Art techniques refer to the various methods and skills artists use to create their work. These can include painting, drawing, sculpting, and printmaking, each requiring different tools and materials. For example, in painting, artists might use acrylics, watercolors, or oil paints to achieve different effects and textures on canvas. Another important aspect of art techniques is the use of color theory and composition. Artists learn how to mix colors and arrange elements in their artwork to create balance and harmony. Techniques like perspective help in creating depth, making a two-dimensional piece appear more lifelike and engaging to the viewer.
