Representing hierarchical relationships through color combinations

Quick answer：

Color combinations can be used to convey hierarchical relationships in design and aesthetics. For example, in graphic design, a color hierarchy can be established by using a dominant color for the most important elements and lighter or complementary colors for less important ones. In architecture, different shades of the same color can indicate different levels of importance or function in a building. This concept is also applied in branding and user interface design to guide user attention and interaction.
