What happens if I mix blonde and brown hair dye?

two colors light and dark

A few days ago, the idea came to mind to change my hair color, and I asked myself what would happen if I mixed brown hair dye with blonde.


The truth is that I wasn’t looking for a platinum blonde; I left that for more audacious women and the ones that have no problem being the center of the universe when they walk into a place.

I also didn’t want a brown tone because it’s pretty common and doesn’t give you something special.


 I wanted something more personal, a unique tone that would make my almond eyes pop without abandoning my brown roots. 

Yes, I know, we women are incredible creatures. That’s why we are the inspiration for great novels and historical events.


My goal was to find a tone that wasn’t blonde nor brown.

Knowing what I wanted was easy, now finding it was another thing.

But in addition to incredible beings, women are bold, and we always put our all into getting what we want. Today I’ll tell you:

  • Why you should try mixing two different color dyes
  • How to mix the two different tones of dye
  • What color I finally got when I combined blonde and brown


It’s time to lose your fear and mix the two dyes. Dare to be unique!

What happens when you mix a blonde dye with a brown one

Let me tell you something to get rid of the myths once and for all.

If you mix two different colors, in reality, nothing bad will happen. The world won’t break into a thousand pieces, and you won’t create a destructive hair bomb.

In the end, you’ll be doing what all the colorists in beauty salons do.


 They play with colors, they mix them, improvise with them, they look to personalize the color for their clients. 

But if you are like me, meaning, one of those that mix different colors in their home, you will save a lot of money.

Because let’s be honest: colorists are professionals, but they aren’t infallible. Often, even though they feel like they’ve gotten a divine color, after looking in the mirror, you feel like it’s a disaster.

To mix different color dyes, you have to keep in mind a few basic principles of colorimetry, meaning the science of colors, graphed out in what is known as the color wheel.


  • First off, it’s important to choose tones that complement each other, instead of two opposite tones.
  • For example, a red tone and a brown tone make each other stand out and produce an intense and deep copper color.
  • Of course, you should avoid mixing black and blonde because both are very dominant colors and don’t mix well.


When mixing two blonde tones of different levels, remember that the higher level will lighten will the lower level add depth.

This brings us to the second question.


How to mix two different dye tones, for example, a blonde and a brown

To dominate the theory of colorimetry, and so that the color wheel doesn’t do us wrong, it is necessary to remember two basic principles: the level and the tone of the color.


Level of color of the hair

The “level” of hair color is relative to lightness or darkness.

All hair colors have levels, whether we are talking about natural color or choosing a new one.

Standard hair color levels are defined on a scale from 1 to 10, with level 1 being the darkest, the most black, and level 10 is a very light blonde.

The scale is issued in the entire beauty industry and is used in brands and formulas of the most well-known brands.

Here are the 10 levels of standard color:

  • Level 1: Black
  • Level 2: Dark Brown, almost black
  • Level 3: Dark brown
  • Level 4: Medium Brown
  • Level 5: Light Brown
  • Level 6: Dark blonde
  • Level 7: Medium Blonde
  • Level 8: Light Blonde
  • Level 9: Very light blonde
  • Level 10: Platinum blonde


So, if we mix a level 6, or a dark blonde, with a level 3, light brown, the objective is to give a bit more depth to the color, making it darker.

I recommend that when you mix the tones, you don’t mix ones that are far away from each other, meaning never mix a level 2 tone with a level nine.


Now, color theory is a bit more complicated, thanks to the tones.

Do you want to know what they are?


Skin tone

After establishing the level of color of the natural hair or the color you want, we should check the tone.

Tones of the hair are generally divided into three standard categories: warm, cold, and neutral.

When stylists talk about color, or if you are choosing a color for an example book, the tones are usually shown with a letter. Here are examples of the standard color tones:


Cold Tones

  • A: Ashy
  • B: Beige
  • B: Blue
  • G: Green
  • V: Violet


Warm Tones

  • C: Copper
  • G: Gold
  • O: Orange
  • R: Red
  • W: Warm
  • RB: Red/Brown
  • RO: Red/Orange


Neutral Tone

  • N: Neutral, not warm or cool

These tones are combined frequently to create the perfect tone or at least the one you want.

For example, brown color is achieved by combining neutral or warm tones with red tones.

Red hair can be colder when you add violet tones to the color formula.


Combining Level and Tone

The technical name of a hair color is a combination of letters and numbers that mark the level and tone.

For example, warm brown color is defined as “7W.” The number indicates the color’s level, dark blonde, and the letter indicates that the tone is warm.

Here, I’ll put some other examples of hair color defined by level or tone:

  • 8A: Medium ashy blonde
  • 4RV: Dark red/violet
  • 6C: Light Brown
  • 5N: Neutral Brown
  • 9W: Warm


Determining the level and tone of your hair color

To calculate the color level of the hair is pretty simple once you learn how to do it.


The most important thing to remember is that hair color isn’t flat. It’s a complex game of depth and tonality that can increase or decrease your skin color and characteristics.

Upon mixing the hair color tones, you should put them in a clean bowl and be sure that they are well-mixed before applying them to your hair.

Lastly, remember that it is always better to choose tones that complement each other instead of two opposite tones.


Finally, do you want to know how I could mix a blonde color with a brown one?

The answer isn’t straightforward.

In reality, I got a very personal tone, which changed tonality according to how the light fell on my hair. The tone also changed depending on if it was night or day.


Meaning, in the full light of day, my hair had a pretty dark tone, and some of the highlights looked darker.

On the other hand, if you looked at my hair at night, that lightness disappeared, leaving a more uniform, dark brown.


  • Mixing two different hair dyes is ideal for getting different tones of color in the same hair.
  • It also helps to personalize the color to match it with your personality.
  • And last but certainly not least, it gives depth to the hair.


In the end, mixing different hair dyes is 21st-century alchemy.

Have you ever mixed two different dyes together? What new tone did you end up with?
