Adjacent color pairing 180 degrees

Quick answer：

Adjacent color pairing refers to the technique of combining colors that are next to each other on the color wheel. The term '180 degrees' suggests a more extreme form of this technique, where colors that are directly opposite each other on the color wheel are paired. This creates a high-contrast, vibrant look. In interior design, fashion, and art, such pairings can be used to create striking visual effects.
