Color coordination - red and green

Quick answer：

Color coordination involves the harmonious blend of different hues to create an aesthetically pleasing effect. Red and green are complementary colors, meaning they are placed opposite each other on the color wheel and can create a striking contrast when used together. This combination is often used in design to attract attention or convey a festive mood. In art and fashion, the red-green combination can evoke a range of emotions, from excitement to restlessness.
