• The number/s after dash relates to tone or pigment added ie the colour you can see red, violet ​
• ​The first number after dash is :- primary tone​
• ​The second number (if any) after dash is :- secondary tone​
• Some also have a third tone
• ​The primary is the strongest tone in the colour​ as its the first after the - or / or .

Navigating the numbers

The depth is always before the point or dash etc 

Tones will be after this 

Some manufacturers have 1-3 numbers representing balance of tones but the tone that sits first will always be more dominant

Some manufacturers also have letters 

Using the numbering system ​

Base colours eg 5/0, 6/0 etc can be used on their own or used for normal grey coverage ​

Double base eg 4/00, 5/00 these are used for resistant grey coverage (this tends to be thick and coarse)​

Most manufacturers recommend up to base 9 to 100% grey coverage 

These bases can be used on their own or mixed into another shade
