Color relationships refer to how colors interact with one another in various contexts, such as art, design, and nature. These relationships can create harmony or contrast, influencing the mood and perception of a composition. Common types include complementary colors, which are opposite each other on the color wheel, and analogous colors, which are next to each other. Understanding color relationships is essential for effective visual communication. For example, primary colors like red, blue, and yellow can be mixed to create secondary colors such as green, orange, and purple. This knowledge helps artists and designers make informed choices about color combinations to achieve desired effects.
