What color is typically used to neutralize yellow tones in hair?

The color that is typically used to neutralize yellow tones in hair is purple. In color theory, each color has a corresponding opposite color, known as its complementary color, which can neutralize its hues. Yellow is a warm color, and its complementary color is purple, which is cool. When purple is applied to yellow-toned hair, it helps to balance out and counteract the yellow, resulting in a more neutral tone.

In the context of hair coloring, purple shampoos and conditioners are commonly used to maintain blonde, silver, or gray hair by reducing unwanted yellow tones. This application of purple pigment is essential for achieving and maintaining desired hair color outcomes, particularly for those with lightened or highlighted hair. Understanding this principle is crucial for effective color correction and achieving the desired results in hair coloring practices.
