Matching color scheme images refer to the use of a color scheme in photography or graphic design. A color scheme typically consists of a set of harmonious colors that work well together. These schemes can range from monochromatic (using different shades of a single color) to complementary (using colors that are opposite each other on the color wheel). In design, a well-chosen color scheme can evoke emotions, highlight certain elements, and make the overall composition more visually appealing.
