colors that go well together

Quick answer：

Color coordination is the process of selecting colors that complement each other. This can be achieved by using colors from the same color wheel family, or by combining contrasting colors. For instance, complementary colors (such as blue and orange) are opposite each other on the color wheel and create a striking contrast when paired together. Analogous colors (like blue, blue-green, and green) are next to each other on the color wheel and provide a harmonious blend. Choosing the right colors for a particular context or design can greatly enhance visual appeal.
