App interface adjacent color matching

Quick answer：

Adjacent color matching in app interfaces refers to the selection and arrangement of colors that are next to each other on the color wheel. This approach can enhance the aesthetic appeal and user experience of an app. It involves choosing colors that complement each other, such as analogous colors (those next to each other on the color wheel) or complementary colors (those opposite each other on the color wheel). Properly matching adjacent colors can create a harmonious and visually appealing design, while poor color choices can lead to a cluttered or unappealing interface.
