Hair Color Mixing Chart: Level + Tone Rules

When mixing two hair dyes, the resulting level is the weighted average of both levels (a 7 + a 9 in equal parts gives an 8). The reflects interact according to the color wheel: similar tones (golden + copper) blend together, while opposite tones (ash + golden) neutralize each other. Understanding these rules is fundamental for predicting results.

Golden Rules for Mixing Hair Colors

Stay within 2-3 levels of difference between the shades you mix. Always use the same brand and line (mixing permanent with demi-permanent gives unpredictable results). Understand underlying pigments: when mixing ash with golden, you don't get "ash-golden" but a more neutral tone, because the blue in ash neutralizes the yellow in golden.

What Happens When You Mix Opposite Tones?

Opposite tones on the color wheel neutralize each other. Ash (blue) + golden (yellow) = neutral. Violet + golden = iridescent pearl. Red + matte (green) = warm neutral. This neutralization is the foundation of color correction: to eliminate an unwanted reflect, mix in its opposite. That's why ash cancels orange and violet cancels yellow.

Classic Color Mixes Every Colorist Should Know

Shade A Shade B Ratio Result Rationale
7/1 (Ash Blonde) 7/3 (Golden Blonde) 1:1 Neutral Beige Blonde Ash and golden neutralize each other, creating a highly requested natural beige.
6/3 (Dark Golden Blonde) 6/4 (Dark Copper Blonde) 2:1 Dark Honey Blonde Golden + copper are close warm tones. More golden gives a luminous honey tone.
5/0 (Light Brown) 5/6 (Light Red Brown) 1:1 Warm Chocolate Brown The natural base softens the red intensity, giving a warm chocolate.
8/1 (Light Ash Blonde) 8/3 (Light Golden Blonde) 2:1 Light Champagne Blonde More ash than golden gives a cool, elegant champagne tone.
7/4 (Copper Blonde) 7/6 (Red Blonde) 1:1 Intense Copper-Red Blonde Copper and red are warm neighbors: they enhance each other.
6/1 (Dark Ash Blonde) 6/7 (Dark Matte Blonde) 1:2 Dark Green-Ash Blonde Ash and matte reinforce each other. Ideal for neutralizing persistent orange.

Frequently Asked Questions

Everything you need to know before getting started

It is not recommended. Each brand has its own chemical base and pigments. Mixing different brands can give unpredictable results. Always use the same brand and, preferably, the same product line.
The result is inconsistent. Permanents need peroxide (6%, 9%, etc.) while demi-permanents use milder activators (1.9-4%). The chemistry of the mixture is altered and the color deposit is not uniform.
Yes. In a 1:1 mix of level 6 and level 8, the result will be level 7. But in a 2:1 mix (more of level 6), the result will be closer to 6.5. The ratio weights the result toward the shade with the greater amount.
It is a prediction based on professional colorimetry. The actual result depends on many additional factors: hair porosity, color history, underlying pigment, processing time and specific brand. Use this tool as guidance and adjust according to your professional experience.
Yes, although it is not common. Professionals sometimes use 3-shade mixes for very specific results. With this calculator you can do sequential mixes: first mix A+B, then use that result as the new shade A and mix with C.
The brand converter finds equivalents of the same shade in different brands. This tool predicts what happens when you mix two different shades. They are complementary: first convert between brands if needed, then predict the mix.
