An application of which colors would help rid a client of unwanted orange tones?

• A. Green-Based
• B. Brown-Based
• C. Blue-Based
• D. Black-Based

Answer: (C)

Blue-based colors are the best choice because orange sits opposite blue on the color wheel. Using blue pigment cancels out the orange warmth, helping to neutralize brassy tones in the hair. In practice, you’d apply a blue-based toner or glaze at the appropriate level to counteract the orange without overshooting to an unwanted cool shade. Green-based products target red tones, brown-based products add depth rather than neutralize orange, and black-based products would simply darken the hair rather than correct the tone.
