How To Read The Numbers In Hair Color

Let’s start by talking about the numbering system.

Most hair colors are numbered on a level system between 1 and 10. Level 1 is black, and as the number gets higher, the color gets lighter.

In other words, it has to do with the lightness or darkness of the color.

While some color lines go up to level 12 (for high-lift blondes), the basic numbering system goes to level 10, which is the lightest shade of blonde.

All other numbers represent the hair color shades that fall in between. For instance, level 4 is medium brown, and level 7 is medium blonde.

A few More Things You Should Know

It’s important to note that some color lines may use their own unique tones to differentiate themselves from the competition. In other words, they won’t follow this system to a T.

💡TIP: You can always check with the manufacturer if you’re unsure.

Or you can usually tell what the base color is by the name of the color. For instance, “light ash blonde” usually translates to a higher-level shade of blonde with blue-based ash tones.

The other important thing you should note is that if the color has double tones, like RV, it means that the first tone is more prominent, and the second is added to complement the first.

For example, RV (red-violet), means that the color has mostly red tones with a bit of violet.

So when you put it all together, 5RV means a level 5 shade of Red-Violet (with more red than violet). 10G means a very light golden blonde.

FAQ

What do the numbers mean on hair color? All hair colors are numbered on a level system between 1 and 10; as the number gets higher, the color gets lighter. For example, level 1 is black, level 5 is medium brown, and level 10 is lightest blonde. All other levels represent the shades that fall in between those colors. What do the numbers and letters mean in hair color? The number-letter combinations refer to the levels and tones of the specific hair colors. The number is measured on a scale from 1-10 (1 being black, 10 being lightest blonde). The letter refers to the tone and base pigment of the color.
