The document discusses several key principles of art and design including: - Design refers to the overall visual arrangement of elements in a work of art. Designing well requires careful study. - Harmony is achieved when all elements blend together in a pleasant and unified whole, such as using only organic or geometric shapes. - Balance refers to the distribution of visual weight, which can be symmetrical, asymmetrical, or radial. - Rhythm uses visual repetition to create interest, seen in repeating colors, lines or shapes. - Emphasis draws the eye to the focal point, seen through contrasting colors or lighting. - Proportion concerns the relationship between parts and the whole.
