Which color does blue cancel out in hair color?

In hair color theory, blue is known to neutralize or cancel out orange tones. This is founded on the principles of color theory, which states that complementary colors—those located opposite each other on the color wheel—can neutralize each other. In this case, orange is situated opposite blue, making them complementary colors.

When working with hair color, if a client has an unwanted orange tint, applying a blue-based toner or color can effectively balance out and cancel the orange, producing a more neutral or desirable hue. This is particularly important for color correction, as it allows for a more natural-looking finish that avoids overly warm or brassy tones. Understanding this relationship is crucial for professionals in the field to achieve the best results for their clients.
