Li Sa's complementary color matching

Quick answer：

Li Sa's complementary color matching refers to the art of combining colors in a way that creates harmony and contrast. In design, complementary colors are pairs of colors that, when placed next to each other, contrast with each other and make each other more vibrant. This concept is based on the color wheel, where complementary colors are located directly opposite each other. Common complementary color pairs include red and green, blue and orange, and yellow and purple. Li Sa, in this context, could be a designer or an artist known for their unique approach to using complementary colors in their work.
