As a professional hair color brand available in salons worldwide, Redken uses a numbering system to categorize their huge range of hair color products. The numbers allow stylists and clients to easily identify the type, tone, and intensity of each color formula. Understanding the Redken numbering system is important for achieving your desired hair color results. This article will explain exactly what the different Redken color numbers represent.
The Redken Color Fusion System
Redken COLOR FUSION is Redken’s flagship hair color line. It uses an innovative ionic liquid dye technology to deliver vibrant, long-lasting color with up to 94% gray coverage. The numbers used in the COLOR FUSION system provide information about each formula’s color group, tone, and depth.
Color Groups
The first number in a Redken COLOR FUSION formula indicates the color group:
| 1 | Black |
| 2 | Brown |
| 3 | Red |
| 4 | Copper |
| 5 | Blonde |
| 6 | Beige |
| 7 | Gold |
So a formula starting with a 2 is in the brown family, while a 5 is a blonde shade.
Tones
The second number refers to the tone, describing if the shade leans warm, neutral or cool:
| 0 | Neutral tone |
| 3 | Beige, gold tone |
| 4 | Warm, copper tone |
| 5 | Ash, cool tone |
| 6 | Ash beige tone |
| 7 | Violet tone |
For example, 53 is an ash blonde while 64 is an ash beige blonde.
Depth
The third number indicates the depth of color:
| 1 | Extra light |
| 3 | Light |
| 4 | Light to medium |
| 5 | Medium |
| 6 | Medium to dark |
| 7 | Dark |
Putting this together, 534 would translate to a light ash blonde, while 665 is a medium to dark ash beige blonde.
Shades EQ Gloss and Demi-Permanent Color
Redken Shades EQ is a gloss and demi-permanent hair color designed to enhance or refresh color treated hair. It uses a lower volume developer than permanent color for a gentler formula. The Shades EQ numbering system is slightly different than Color Fusion:
Level System
The first number still references the depth, but on a level system from 1 to 10:
| Level 1 | Black |
| Level 2 | Darkest brown |
| Level 3 | Dark brown |
| Level 4 | Medium brown |
| Level 5 | Medium blonde brown |
| Level 6 | Light brown blonde |
| Level 7 | Dark blonde |
| Level 8 | Medium blonde |
| Level 9 | Very light blonde |
| Level 10 | Lightest blonde |
Tone Letter
The second character is a letter indicating the tone:
| N | Neutral |
| G | Gold |
| A | Ash |
| V | Violet |
| C | Copper |
For example, 7N is a level 7 neutral blonde, while 5G is a level 5 gold brown.
Redken Chromatics Permanent Hair Color
Redken Chromatics is a salon-quality permanent hair color delivering predictable results with up to 100% gray coverage. It uses an oil delivery system to condition and protect hair during the coloring process. The Chromatics numbering system works as follows:
Level Number
The first part of the number is the level from 1 to 10, with 1 being the darkest black through to 10 for lightest blonde.
Tone Letter
The tone letter follows the level number using N for neutral, G for gold, A for ash, C for copper, and V for violet tones.
Intensity Number
The final digit indicates the intensity of the tone. Higher numbers mean more intense or opaque coverage:
| 0 | Natural tone |
| 1 | Low intensity |
| 2 | Medium intensity |
| 3 | High intensity |
As an example, 7N3 would be a high intensity neutral blonde at level 7. 5A1 is a low intensity ash brown at level 5.
Redken Shades EQ Cream Hair Color
Redken Shades EQ Cream is another demi-permanent, conditioning formula that blends gray and enhances tone. It uses a unique multi-spectrum technology to provide soft, natural results. Here is what the numbers mean:
Level Number
Again, the level number ranges from 1 to 10, with 1 being black through to 10 for pale blonde.
Tone Letter
The tone letter uses N for neutral, G for gold, A for ash, C for copper and V for violet.
For the Cream formula, a number is not needed after the tone letter because these demi-permanent shades provide subtle, translucent coverage.
So an example would be 8A for an ash tone at level 8 blonde.
Redken pH-Bonder Additives
Redken pH-Bonder is a patented additive that helps bond hair’s disulfide bonds before coloring for stronger, healthier hair. There are two versions:
Redken pH-Bonder Additive
This pre-color additive is used in permanent hair color and comes in different “plus” numbers:
| Plus 0 | For fragile hair |
| Plus 1 | For damaged hair |
| Plus 2 | For very damaged, compromised hair |
Choose the plus number based on the condition of your hair to help prevent breakage and damage during lightening and coloring services.
Redken pH-Bonder Primer Additive
The Primer version is infused into the developer to strengthen and protect hair when using REDKEN Chromatics, COLOR FUSION or BLONDE IDOL permanent hair color. The primer comes in three “plus” numbers:
| Plus 0 | For processed hair |
| Plus 1 | For damaged hair |
| Plus 2 | For overprocessed hair |
Choose the primer plus number based on your hair’s current condition and processing level.
Blonde Idol Lightener
Redken Blonde Idol is a professional lightening system designed to lift hair up to seven levels with cool, conditioning technology. It is available in powder lightener as well as quick-mixing cream formulas. Here is what the Blonde Idol numbers mean:
Level Numbers
The first part of the number refers to the starting level of hair color:
| 2 | Level 2 darkest brown |
| 3 | Level 3 dark brown |
| 4 | Level 4 medium brown |
| 5 | Level 5 medium brown |
| 6 | Level 6 light brown |
| 7 | Level 7 dark blonde |
Volume Numbers
The second part of the number is the volume of developer used to determine lifting power:
| 10 | 10 Volume (3%) |
| 20 | 20 Volume (6%) |
| 30 | 30 Volume (9%) |
| 40 | 40 Volume (12%) |
So “Blonde Idol 7/20” would lighten level 7 dark blonde hair using 20 volume developer. “Blonde Idol 4/40” uses 40 volume to maximize lifting on level 4 hair.
Redken Shades EQ Sealing Gloss
Redken Shades EQ Sealing Gloss is a shine-enhancing glossing treatment. It comes numbered as follows:
Clear Gloss
Shades EQ 000 is a crystal clear gloss with no tint or toning.
Tinted Glosses
Numbers 010 through 120 provide sheer soft toning in ash, gold and neutral shades.
Redken Color Extend Brownlights and Blonde Idol Custom-Tones
Brownlights and Custom-Tones are part of Redken’s Color Extend salon exclusive line of toning and glossing services. The numbering system is simple:
Levels
The first number is the level from 1 to 10.
Tone Letter
The tone letter uses N for neutral, G for gold, A for ash, C for copper, V for violet.
So “Blonde Idol Custom-Tone 9N” provides an icy toning service for level 9 blondes.
Redken Shades EQ Gloss Refresh
Shades EQ Gloss Refresh is a do-it-yourself demi-permanent glaze designed to revitalize color and shine at home between salon visits. The easy brush applicator bottles are numbered as follows:
Levels
The number indicates the depth level from 1 to 10.
Tone Letter
The tone letter uses N for neutral, G for gold, A for ash.
So “Shades EQ Gloss Refresh 7G” provides a refreshing gold demi-glaze for level 7 dark blondes.
