Color combinations can greatly enhance visual appeal in various contexts, such as interior design, fashion, and graphic design. A popular method is the color wheel, which divides colors into primary, secondary, and tertiary categories, and shows how they relate to each other. Here are four beautiful color combinations: 1. Complementary colors (e.g., blue and orange) create high contrast and are eye-catching. 2. Analogous colors (e.g., red, orange, and yellow) are harmonious and soothing. 3. Split complementary colors (e.g., blue, orange, and yellow) offer a balanced mix of contrast and harmony. 4. Triadic colors (e.g., red, blue, and yellow) provide a vibrant and dynamic look.
