The elements of art include line, shape, form, value, texture, color, and space. Understanding these elements is important for both artists and viewers to have a deeper appreciation and understanding of artworks. The key elements are line (mark on a surface), shape (two-dimensional figure), form (three-dimensional figure with height, width and depth), value (lightness or darkness of a color), texture (feel of a surface), color (hue associated with light), and space (emptiness of positive and negative space).
