Complementary color tinting

Quick answer：

Complementary color tinting refers to the process of adding a tint to a complementary color to create a new shade. In color theory, complementary colors are pairs that, when combined, produce a grayscale. For instance, blue and orange are complementary colors. Tinting involves adding white to a color to lighten it, while shading involves adding black to darken it. This technique is often used in art and design to create contrast and harmony.
