A color scheme is a planned combination of colors used in design, art, or fashion to create a specific visual effect. It helps to establish mood, convey messages, and enhance aesthetics. Common types of color schemes include complementary, analogous, and monochromatic, each offering different visual dynamics. Choosing the right color scheme is essential for effective communication and branding. For example, blue often evokes feelings of calmness, while red can signify energy or urgency. Designers use color theory principles to select colors that work harmoniously together, ensuring that the overall composition is visually appealing and impactful.
