Color contrast and balance techniques are essential principles in design that enhance visual appeal and communication. Color contrast involves using differing hues, tones, or intensities to create visual interest and draw attention to specific elements within a composition. High contrast can emphasize key areas, while low contrast can create harmony and subtlety. Balance, on the other hand, refers to the distribution of visual weight in a design, which can be achieved through symmetrical arrangements (where elements are mirrored) or asymmetrical layouts (where different elements are arranged to create an overall sense of equilibrium). Together, these techniques help guide the viewer's eye, evoke emotions, and create a cohesive and aesthetically pleasing visual experience.
