You’re standing in the beauty supply store, staring at a wall of synthetic hair that seems to stretch on for miles. It’s a lot. You just wanted a nice honey blonde for your knotless braids, but instead, you're faced with a cryptic code of numbers like 27, 30, 613, and 1B. Honestly, if you don’t know what you’re looking at, you might end up with a head of hair that looks nothing like the Pinterest board you showed your stylist. Hair color numbers for braids aren't just random digits thrown on a pack of Kanekalon; they are a universal language used by manufacturers like Outre, X-Pression, and RastAfri to ensure consistency across the globe.
Getting the wrong shade is a nightmare. Imagine spending six hours in a chair only to realize in the sunlight that your "dark brown" braids are actually a harsh, blue-tinged black. It happens more than you'd think.
The Basic Logic of the Numbering System
Most people think the numbers are just arbitrary. They aren't. The system actually stems from the professional hair coloring scale, though synthetic hair brands take some liberties. Generally, the lower the number, the darker the hair.
Number 1 is the deepest, purest black you can find. It’s often called "Jet Black." It has a cool, almost blue undertone that can look a bit "wiggy" if it doesn't match your natural hair perfectly. Then you have 1B. This is the holy grail for most people. The "B" stands for "Off Black," and it’s basically the color of most natural human hair. It’s got a hint of warmth that makes it look like it actually grew out of your scalp.
If you move up to 2 and 4, you’re entering the brunette territory. Number 2 is a very dark brown, while 4 is more of a medium "chocolate" brown. A lot of braiders prefer using 4 for a softer look on clients who find black too harsh against their skin tone.
Why Sub-Tones Matter More Than the Base
It gets tricky when you hit the 20s and 30s. This is where most people get confused about hair color numbers for braids.
- 27 is Strawberry Blonde. It’s warm, golden, and has a lot of red influence.
- 30 is Medium Auburn. Think of a copper penny or a fallen leaf. It’s brown but with a heavy dose of orange/red.
- 33 is Dark Auburn. This is the "True Copper" or "Cherry Cola" vibe. It’s deeper and more sophisticated than 30.
I’ve seen people mix 27 and 30 to get a dimensional "bronze" look, and honestly, it’s one of the best combos for summer. If you just use 27, it can look a bit flat. Mixing them adds that "expensive" look we all want.

The Blonde Ambition: 613 and Beyond
Then there is the 613. If you know, you know. 613 is the "Platinum Blonde" or "Bleach Blonde" number. It’s iconic, bold, and high-maintenance. Because synthetic 613 is so light, it shows every single braid stray and every bit of your natural hair if it isn't tucked perfectly.
Some brands have introduced 614 or even "Ice Blonde" shades, but 613 remains the industry standard. If you want something a bit more toned down, you look for a 24 or a 22, which are more "ash" or "honey" blondes. They don't scream for attention quite as loudly as 613 does.
Trends and T-Colors: The Ombre Effect
Lately, the market has shifted. We aren't just buying solid packs anymore. You’ll see packs labeled T1B/27 or T1B/30. The "T" stands for "Two-tone" or "Tip." This is your pre-stretched, pre-colored ombre hair.
It’s a lifesaver. Back in the day, stylists had to manually "taper" different colors together to get an ombre effect. It took forever. Now, the transition is baked into the fibers. The first number (usually 1B) is the root color, and the second number is the color at the tips.
But here’s a tip: not all T-colors are created equal. Some brands have a very "harsh" line where the color changes. If you want a seamless blend, you have to look for "Piano" colors or "Sunkissed" mixes. These use a "P" prefix (like P4/27) and indicate a highlighted or streaked effect rather than a solid dip-dye look.
The Science of Synthetic Fibers
We should talk about what this stuff is actually made of. Most braiding hair is Kanekalon or Toyokalon. These are modacrylic fibers. The way they take pigment is totally different from human hair.

According to a study on synthetic fiber aesthetics in the Journal of Engineered Fibers and Fabrics, the "luster" of these fibers affects how we perceive the color number. This is why a "4" in one brand might look shinier and therefore "lighter" than a "4" in another brand. It’s all about light reflection. When you’re choosing your hair color numbers for braids, try to stick to one brand for the whole head. Mixing an Outre 1B with a Sensationnel 1B can result in a weird, patchy finish because their factory dyes and fiber coatings differ.
The "Secret" Reds and Purples
If you’re feeling spicy, you move into the 99J and 350 territory.
99J is "Black Cherry" or "Burgundy." It’s a deep, wine-red that looks incredible on dark skin. It’s subtle indoors but "pops" like crazy under the sun.
350 is the "Bright Copper" or "Ginger" that went viral a couple of years ago. It’s loud. It’s bright. It’s basically the color of a sunset. Then you have the "Bug" (short for Burgundy), which is usually a bit brighter than 99J.
What most people get wrong is thinking these colors will look the same on everyone. Skin undertones play a massive role here. If you have cool undertones (veins look blue), 99J will look stunning. If you have warm undertones (veins look green), a 350 or 30 will likely look more "natural" on you.
Don't Forget the Grays
Gray hair used to be something people tried to hide. Not anymore.
Number 44 and 51 are the go-to choices for the "Silver Fox" look.
44 is a salt-and-pepper mix (mostly dark with gray highlights), while 51 is a much lighter, pearlescent gray.
280 is another one—it’s a dark charcoal with just a hint of gray. Using these for braids is a huge power move. It looks intentional and chic.
Real World Expert Advice: The "Tuck" Factor
Here is the thing your stylist might not tell you: your natural hair color dictates what numbers you can actually pull off.

If your hair is jet black and you choose 613, your "tuck" has to be flawless. "Tucking" is the technique where the stylist hides your natural hair inside the synthetic braid. If you aren't great at tucking, and your black hair is peeping out of a blonde braid, it looks messy.
If you're a DIY-er, stick to colors that are within two shades of your natural hair. If you're a 1B, try a 2 or a 4. It’ll look much more seamless even if your technique isn't 100% perfect.
Texture and Light
Light hits different textures differently. A color 27 in a "Deep Wave" bulk hair for boho braids will look different than a color 27 in a "Pre-stretched" straight XPression pack. The curls catch more light, making the color appear more vibrant. Straight hair can sometimes make the color look a bit flatter or darker. Always pull a strand out of the pack and hold it against your forehead in the natural light of the store window. The fluorescent lights in beauty supply stores are notorious for lying to you.
Moving Beyond the Standard Palette
We are seeing a lot more "custom" mixes now. Brands like Adora or Ruwa are coming out with names like "Caramel," "Chocolate Frost," and "Mocha."
While these names sound pretty, always look for the small print on the back of the pack. It will almost always have the standard hair color numbers for braids listed there. For example, "Mocha" might actually be a 4/30 mix. Knowing the numbers allows you to recreate that look even if that specific brand is out of stock. You just buy a pack of 4 and a pack of 30 and have your stylist "mix" them on the rack.
Actionable Steps for Your Next Braiding Appointment
Don't just walk in and hope for the best.
- Identify your natural level. Are you a 1 (Jet Black), 1B (Off Black), or 2 (Dark Brown)? This is your "anchor" color.
- Decide on the vibe. Do you want a "natural" look (stay within 2 numbers of your anchor) or a "statement" look (go for 27, 30, 613, or 350)?
- Check the undertone. If you want brown, do you want a "cool" brown (Color 2) or a "warm" brown (Color 4 or 30)?
- Stick to one brand. Buy all your packs from the same manufacturer to avoid "sheen mismatch."
- Test the "Tuck." If you're going way lighter than your natural hair, ensure your stylist is skilled in the tucking technique or consider a "boho" style where some of the natural hair peeking out is less noticeable.
- Take a photo of the pack. Once you find your "signature" color, take a photo of the label. Store it in a "Hair" album on your phone. You’ll thank yourself in three months when you can't remember if you liked 27 or 30 better.
Understanding this numbering system takes the guesswork out of the process. It turns a stressful shopping trip into a quick errand. Once you master the numbers, you're no longer at the mercy of whatever the store clerk recommends; you’re the one in control of your look.
