Hair Color Numbers Explained: How To Read a Hair Color Chart?

October 28, 2024

Reading a hair color chart can seem complex at first, but it becomes straightforward once you understand the system used by most hair dye manufacturers. Typically, hair colors are represented using a numbering system that includes both a base number and a series of digits or letters that denote specific characteristics such as tones and shades.

Here’s a general guide on how to read a hair color chart:

Base Number

The base number usually represents the main color tone or level of darkness. This is often represented by a single digit, starting from 1 (the darkest black) to 10 (very light blonde or white).

Sub-number or Modifier

After the base number, there can be additional numbers or letters which indicate variations in tone and shade. These modifiers can range from natural tones to highlights and lowlights.

Examples:

  • 1 - Black
  • 2 - Dark Brown
  • 3 - Medium Brown
  • 4 - Light Brown
  • 5 - Dark Blonde
  • 6 - Medium Blonde
  • 7 - Light Blonde
  • 8 - Very Light Blonde
  • 9 - Platinum Blonde
  • 10 - White Blonde

Tones

Numbers or letters following the base number indicate the tone of the color:

  • 0 - Natural
  • A - Ash
  • B - Beige
  • C - Copper
  • D - Dark
  • E - Neutral
  • F - Gold
  • G - Golden
  • H - Mahogany
  • I - Pearl
  • M - Mocha
  • N - Neutral
  • P - Pearl
  • R - Red
  • S - Sandalwood
  • T - Taupe
  • V - Violet
  • W - Wheat
  • X - Caramel
  • Y - Yellow

For example:

  • 4.0 - Light Brown (Natural)
  • 5.12 - Dark Blonde with Pearl Tone
  • 6.33 - Medium Blonde with Intense Copper Tone
  • 7RG - Light Blonde with Red/Golden Tone

Some brands might use slightly different systems, so always refer to the specific instructions provided by the manufacturer of your chosen hair dye.

Understanding these codes allows you to select the right color for your desired outcome. Always consider consulting with a professional stylist if you're unsure about the process or need personalized advice.
