Understanding Hair Color Codes

Hair color codes are a standardized system used in the beauty industry to precisely define and communicate different hair colors. This system serves a crucial purpose by providing a universal language for hair colorists, allowing them to achieve consistent results and meet clients' expectations.

In this system, each hair color is represented by a unique combination of numbers and letters, typically ranging from 1 to 10 and including additional letters. The numbers represent the depth or darkness of the color, while the letters signify the underlying tones or undertones.

"1B" and "2" are two specific shades within this coding system:

  1. 1B hair color: This shade represents a deep, rich black hair color. It is a popular choice for those seeking a classic and timeless look. The "1" in "1B" indicates the darkest depth, which is black, while the "B" denotes a subtle blue undertone. This blue undertone can provide a sense of coolness to the black hue, making it less flat and more multidimensional.
  2. 2 hair color: The shade "2" signifies a very dark brown hair color. It's a step lighter than 1B and is often chosen by individuals looking for a softer alternative to pure black. While "2" represents the depth, the absence of any letters suggests a neutral undertone. This means it lacks the distinct undertones of red, gold, or blue, making it a versatile and natural-looking shade.

These codes help individuals and professionals make informed choices about the exact hair color they desire, ensuring that the result aligns with their preferences and complements their skin tone.

Characteristics of 1B Hair Color

1B hair color is a distinctive shade with several key characteristics that set it apart in the realm of hair color options. Understanding these characteristics can help you determine if 1B is the right choice for your style.

Depth: 1B is one of the deepest and darkest hair colors available. It is often described as a rich, intense black. This depth provides a sense of drama and contrast, making it a striking choice for those who want their hair to make a bold statement.

Undertones: What distinguishes 1B from plain black is its subtle undertone. The "B" in 1B stands for "blue," indicating that this shade has a cool, slightly bluish undertone. This undertone adds depth and dimension to the black, preventing it from appearing flat or one-dimensional. It also contributes to a cooler, more sophisticated look compared to a pure, warm black.

Appearance: 1B hair color has a glossy and reflective appearance that can be truly eye-catching. When the light hits this shade, it often reveals hints of deep blue undertones, creating a visually intriguing effect. This added dimension enhances the overall beauty of the hair and can make it stand out in various lighting conditions.

This shade is particularly suitable for those who want a bold and alluring hair color that exudes confidence and style.

Choosing 1B hair color can be an excellent option if you're looking for a dark, striking hair color that offers a unique twist with its blue undertones. However, it's essential to consider your skin tone and personal style to ensure that 1B complements your overall look effectively.

Characteristics of 2 Hair Color

2 hair color is a beautiful and versatile shade that offers a unique blend of depth and warmth. Understanding its key characteristics can help you decide if this hue aligns with your style.

Depth: Hair color code "2" represents a very dark brown shade. It's a step lighter than pure black, offering depth and richness to your hair without the intensity of black. The depth of this color provides a natural and elegant appearance.

Undertones: What sets 2 hair color apart is its neutral undertone. Unlike many other shades that have warm or cool undertones, "2" typically lacks any distinct undertone. This neutrality makes it a versatile choice that can complement a wide range of skin tones, making it suitable for many individuals.

Appearance: 2 hair color appears as a deep, lustrous brown shade. It has a warmth that gives your hair a natural and inviting look without being too overpowering. In various lighting conditions, it can exhibit different facets, from a warm, almost chestnut hue to a deeper, more traditional brown.

Its neutral undertone makes it a flexible option that can suit a wide range of personal styles and preferences. When considering this shade, take into account your skin tone and style to ensure it complements your overall look effectively.

Factors to Consider When Choosing Between 1B and 2

The decision between 1B and 2 hair colors can be a pivotal one, and it often comes down to personal preferences and how well each option aligns with your unique characteristics and desired look. While both shades offer their own allure, here's a guide to help you make an informed choice:

1B Hair Color:


  • Versatile: 1B hair color, with its deep black shade and subtle blue undertone, strikes a balance between classic and distinctive. It can be an excellent choice for those who want to make a statement while maintaining a semblance of naturalness.
  • Complementing Skin Tones: 1B tends to complement cooler skin tones due to its cool undertone. If your skin has cool undertones, this shade can enhance your complexion.


  • Less Natural: Some may find 1B's deep black to be less natural than a brown shade like 2. If you're seeking a more understated look, it might not be your ideal choice.

2 Hair Color:


  • Natural appearance: 2 hair color, a very dark brown, exudes a natural and elegant vibe. It's versatile and harmonizes well with various skin tones, making it a safe bet for many individuals.
  • Low Maintenance: 2 often requires less maintenance than deeper shades like 1B, making it an excellent choice for those looking for a beautiful yet fuss-free hair color.


  • Limited Boldness: If you crave a dramatic and bold appearance, 2 might seem understated compared to the deep intensity of 1B.
  • Potential for Blending: If your natural hair color is close to 2, achieving noticeable contrast may be more challenging.

Choosing Between 1B and 2:

  1. Consider Your Skin Tone: If you have cooler undertones in your skin, 1B can enhance your complexion. On the other hand, if your undertones are warmer or neutral, 2 may be a more harmonious choice.
  2. Assess Your Desired Look: Are you looking for a bold, striking appearance that makes a statement? In that case, 1B could be your preference. If you prefer an elegant, natural look with lower maintenance, 2 might be more appealing.
  3. Maintenance and Versatility: Consider your lifestyle and how much time you want to invest in hair maintenance. If ease of maintenance is a priority, 2 hair color may be the better fit.
  4. Matching Your Natural Color: If you're looking for a color that closely matches your natural hair or want a seamless transition from your roots, 2 could be the choice for you.
  5. Hair Extension Health: If you plan to use hair extensions, consider which color will blend seamlessly with your natural hair, ensuring a more natural and healthy appearance.
  6. Matching Your Skin Tone: If your primary goal is to complement your skin tone effectively, take a close look at your undertones and how each color interacts with your complexion.

Ultimately, the right choice between 1B and 2 depends on a combination of factors, including your skin tone, desired look, and lifestyle. Both shades have their unique charm, so consider these fators carefully to make a decision that enhances your beauty and style.

Tips for Maintaining 1B and 2 Hair Colors at Home:

Tip 1: Use Color-Safe Products: Opt for sulfate-free shampoos and conditioners designed for colored hair. These products help maintain the vibrancy of your chosen shade.

Tip 2: Wash with Cool Water: Hot water can strip color from your hair. Wash your hair with cool or lukewarm water to prevent premature fading.

Tip 3: Reduce Washing Frequency: Washing your hair less frequently can extend the life of your color. Consider using dry shampoo between washes to keep your hair feeling fresh.

Tip 4: Protect Your Hair from the Sun: UV rays can cause color fading. Use UV-protective hair products or wear a hat when exposed to direct sunlight.

Tip 5: Avoid Heat Styling: Heat-styling tools like flat irons and curling irons can contribute to color fading. If you must use them, apply a heat protectant spray before styling.

Tip 6: Regular Touch-Ups: To maintain the vibrancy of 1B or 2 hair colors, schedule regular touch-ups as your roots grow out. Follow the same application process as when you initially colored your hair.

Tip 7: Deep Condition Regularly: Treat your hair to deep conditioning treatments once a week or as needed to keep it moisturized and prevent dryness or breakage.

Tip 8: Avoid Chlorine and Saltwater: Chlorine and saltwater can be harsh on colored hair. If swimming, protect your hair with a swim cap or rinse your hair with fresh water immediately after swimming.

By following these steps and using recommended products and techniques, you can achieve and maintain the stunning 1B and 2 hair colors while preserving their vibrancy and health. Regular care and attention will ensure that your hair continues to look its best and showcases the beauty of your chosen shade.
