Which complementary color category helps neutralize brassiness or orange tones in hair color?

• A. Red-based
• B. Yellow-based
• C. Blue-based
• D. Green-based

Answer: (C)

Neutralizing orange or brassiness in hair relies on using a color that is opposite orange on the color wheel. That opposite is blue, so a blue-based category provides the counter-shades needed to cancel warm orange tones. When you apply a blue-based toner or product, it introduces blue pigments that offset the orange, pulling the result toward a cooler, more neutral shade. Using red-based would add warmth, yellow-based would intensify yellow/orange further, and green-based targets red tones in a way that doesn’t effectively cancel brassiness and can muddy the result. So blue-based is the right approach for correcting orange brassiness.
