Using the Color Wheel to Neutralize Unwanted Tones

Almost every tonal correction in the chair is an application of one simple rule: opposite colors cancel each other. Orange is killed by blue, yellow by violet, green by red, and red by green. The art is not knowing the pairs, it is using just enough of the opposite to neutralize without tipping the hair into the new color. This guide covers the pairs and the restraint that makes them work.

The neutralizing pairs

Complementary colors sit directly across from each other on the wheel, and when combined they gray each other out. These pairs are the backbone of every toning and color-correction decision.

Keep this short list in your head and you can diagnose any unwanted tone and reach for its opposite immediately.

• Orange is neutralized by blue
• Yellow is neutralized by violet
• Yellow-orange is neutralized by blue-violet
• Green is neutralized by red
• Red is neutralized by green

Use the smallest effective amount

Neutralizing is a balance, not a flood. A small amount of the complementary tone grays out the unwanted warmth or coolness, but too much swings the hair into the opposite problem, turning brassy hair muddy or green.

Start conservative, process, and assess. You can always add more, but you cannot easily remove an over-correction without lifting again.

Neutralize at the right level

The strength of the neutralizer has to match the depth of the warmth. Pale yellow on a level 9 needs only a whisper of violet, while a stubborn orange level 7 needs a stronger blue base to balance it.

Matching neutralizer intensity to the level of the unwanted tone is what keeps your correction from looking either weak and brassy or heavy and dull.

Mistakes to avoid

• Reaching for violet to fix orange, when orange needs blue.
• Over-toning until the hair turns gray, smoky, or green.
• Using a strong neutralizer on pale, fragile blonde that needs only a touch.
• Trying to neutralize warmth that has not been lifted out yet.

Frequently asked questions

What color cancels out orange hair?

Blue cancels orange because they are complementary on the color wheel. For orange-gold tones, a blue-violet works better since it covers both the orange and the yellow. Use the smallest amount that neutralizes the warmth, since too much blue can leave the hair looking muddy or gray.

What neutralizes green tones in hair?

Red neutralizes green, since they sit opposite each other on the color wheel. Green often appears after lifting blue-black box dye or from mineral and chlorine buildup. A red or red-orange based filler or toner, matched to the level, balances the green back toward a natural tone.
