A color scheme is a planned combination of colors used in design, art, or fashion. It helps create a specific mood or feeling and can enhance the overall aesthetic of a project. Common types of color schemes include complementary, analogous, and monochromatic, each offering a different visual effect. In graphic design, a well-chosen color scheme can improve readability and user experience. For example, a website might use a calming blue and green palette to promote relaxation, while a children's book might feature bright, vibrant colors to attract attention and stimulate imagination.
