The document discusses the visual elements of art that are important to understand when describing artworks. It identifies the key elements as line, shape, color, space, value, texture, time and motion. It then proceeds to define each element in more detail. For example, it defines line as a one-dimensional geometric object, and color as the visual perceptual property deriving from the spectrum of light interacting with the eyes. It also discusses the different color schemes used in art, such as monochromatic, analogous, complementary, split complementary, triadic and square schemes.
