What colors can be formed by combining complemetary colors?

When complementary colors are combined, they typically neutralize each other, resulting in a grayscale color such as brown or gray. This occurs because complementary colors are opposite each other on the color wheel, meaning they contain all the primary colors in varying proportions. In art and design, mixing complementary colors can create muted tones, while in additive color mixing (like light), combining them can produce white light.
