Low purity complementary color matching

Quick answer：

Low purity complementary color matching refers to a color scheme where colors that are close in hue but have lower purity are paired together. This creates a harmonious and subtle contrast. It is often used in design to create a sense of calm and balance. In color theory, complementary colors are pairs that, when combined, cancel each other out, producing a neutral gray. However, in low purity complementary matching, the colors are not pure enough to completely cancel each other out, resulting in a more nuanced and less stark contrast.
