Before buying any box dye that “looks warm” to you, you need to identify your current hair color.

The color scale ranges from black 1 to platinum extra light blonde 10.


  There are also secondary colors like ashy or golden. They’re identified with a number after the dot.  


These secondary colors or underlying pigments are:

  • 1 ash (blue)
  • 2 iridescent / pearlescent (pearl)
  • 3 golden (yellow)
  • 4 copper (orange)
  • 5 mahogany (bordeaux)
  • 6 red
  • 7 metallic (green)


These seven secondary colors are divided into two major groups:

  • Ashy: 1 ash, 2 iridescent, 7 metallic.
  • Warm: 3 gold, 4 copper, 5 mahogany.


This is how the colors are represented in the chart. Now, all you have to do is identify your color.

Which number corresponds to your current hair color?

Light ash brown 5.1?

Ash blonde 7.1?

Why does your current color end with a .1?


Because your hair is ashy, and the number 1 corresponds to the ashy undertone.

So, all you have to identify is the main number of the color you usually dye your hair with.


  Then, just look for a dye with that same main number but with warm undertones. The number after the dot could be 3, 4, and 5.  

How do you know which gold undertone suits you best to warm up your ashy hair?


That’s what I’ll tell you next.


How to choose the ideal warm tone to warm up ashy hair according to your face or style

Once you know your hair color, the options are almost endless. There’s a warm color for every ashy tone to light up more than just your hair.

  • If your skin is very pale, you can choose warm colors like copper or mahogany.
  • If your skin is darker, you can choose gold and red.
  • If your hair is straight, you can choose gold or copper.
  • If your hair is curly, you can choose red or gold.
  • If you have a sophisticated style, gold is ideal for you.
  • If your look is urban, red or auburn will look perfect.
  • If you have a sporty look, gold will look fantastic.


  The color combinations are endless. You can warm up your ashy hair with any of them   for a playful look or to hide imperfections such as high cheekbones.

If you warm up your ashy hair, you’ll lighten your face, hide wrinkles, and look younger.

The most important thing is to respect your hair color level. You can’t apply 5.1 to a light ash brown and 8.3 to a light golden blonde.

The only thing you need to modify is the underlying tones to warm up your ashy hair!


For example:

  • If your hair is a very light ashy blonde 9.1, you can choose a very light golden blonde 9.3 or auburn 9.5.
  • If your hair is a light ash brown 5.1, you can choose a light reddish brown 5.6 or copper 5.4.
  • If your hair is an ash blonde 7.1, you can choose an auburn blonde 7.5 or golden blonde 7.3.

Rinse the dye with cold to lukewarm water until it runs clear.
