Explanation:
Complementary colors are opposite each other on the color wheel (e.g., red and green, blue and orange). They create a strong contrast and are often used to make elements stand out. This type of harmony is dynamic and eye-catching but should be used carefully to avoid visual tension.

Analogous colors are next to each other on the color wheel (e.g., blue, blue-green, and green). They create a harmonious and cohesive look because they share similar hues. This type of harmony is often used to evoke a sense of calm and unity in a design.

Triadic colors are equally spaced around the color wheel (e.g., red, yellow, and blue). They create a balanced and vibrant palette that offers a high level of contrast while maintaining harmony. This type of harmony is often used for lively and energetic designs.
