How to Match Extension Colour to Dark Hair: Natural Black vs 1B vs #2

Choosing the right colour for hair extensions can be harder than choosing the length. Dark shades can look very similar online, but natural black, 1B and #2 are not exactly the same colour.

If you're trying to match extensions to your natural hair, the goal isn't simply to choose the darkest shade. You need to consider whether your hair is true black, a softer off-black, or a dark brown.

For many customers, 1B hair colour sits close to their natural dark hair, but the right choice depends on your own hair colour and how closely you want the extensions to blend.

What Is 1B Hair Colour?

1B hair colour is commonly described as natural black or off-black. It is softer than a very deep jet-black shade and can look more natural when compared with extremely dark black hair.

This is why 1B is often a useful option for people whose hair looks black but isn't a very intense, solid black.

When you're looking at hair extensions, remember that colour can also appear slightly different depending on lighting, your screen and the texture of the hair.

At To All My Black Girls, several extension products are offered in a natural colour described as being between 1B and 2, rather than as a solid jet black.

Natural Black vs 1B: What's the Difference?

The terms can be confusing because different hair brands and colour charts don't always use exactly the same wording.

In general:

The easiest way to think about it is:

#1 → deepest, most intense jet black
Natural Black → very dark black with a more natural appearance
1B → softer off-black
#2 → dark brown

What is the difference between #1 and Natural Black?

The main difference is how intense the black looks. Colour #1 is a very deep, intense jet black, while natural black refers to hair that appears naturally very dark without the strong, artificial-looking intensity of jet black.

If your natural hair has even a slight brown tone in daylight, 1B or a 1B/#2 mix may blend more naturally than a very dark black extension.

Is 1B the Same as Natural Black?

Not always.

1B is generally a soft black or off-black shade, while natural black refers to unprocessed hair that has a softer, naturally occurring black appearance.

The difference can be subtle, especially indoors.

To compare your colour accurately, look at your natural hair in daylight. Pay attention to whether it looks like a soft natural black or has a noticeably deeper, more intense black tone.

The important thing is to compare your natural hair with the extension rather than choosing based only on the colour name. If you're unsure which shade will match, we recommend purchasing our hair samples first so you can compare the colour with your natural hair before purchasing a full set. 

What Is #2 Hair Colour?

#2 is a dark brown shade.

It looks lighter and warmer than 1B, although the difference may be hard to notice under artificial lighting.

If your natural hair has visible brown tones, particularly in sunlight, #2 may be closer to your own colour than a black shade.

However, if your hair is clearly black rather than brown, choosing #2 can create a noticeable contrast.

If you want a specific #2 shade, this colour can also be achieved through our Custom Colour Service. This allows you to request a colour that better matches your natural hair. 

How to Match Hair Extension Colour to Your Natural Hair

The most reliable way to choose an extension colour is to compare the extension with your actual natural hair in good lighting.

1. Check Your Hair in Natural Daylight

Indoor lighting can make dark colours look almost identical.

Stand near a window or go outside and look at your hair without coloured lighting.

Ask yourself:

• Does my hair look completely black?
• Does it have a softer off-black appearance?
• Can I see brown tones?
• Does my natural hair look lighter at the ends?

This gives you a better starting point than comparing colour names alone.

2. Look at Your Mid-Lengths and Ends

Don't only look at your roots.

If your hair has been exposed to sunlight, heat styling or colour treatments, the ends may be lighter than the roots.

This matters because extensions are usually blended into the visible lengths of your natural hair.

For example, your roots may look almost black while your ends have a softer brown tone. Matching only the roots could leave the extensions looking too dark.

3. Compare the Texture as Well as the Colour

Colour isn't the only thing that affects how well extensions blend.

Curly, kinky, and textured hair reflects light differently from straight hair. This can make two similar shades appear slightly different once they're installed.

A colour that looks slightly different in the bundle may blend much more naturally once it is styled with your own hair.

4. Don't Judge the Colour From One Photo

Online product photos can be helpful, but they aren't a perfect colour-matching tool.

Your screen brightness, room lighting, and camera settings can all affect how a dark shade appears.

If you're unsure between two shades, compare the colour under natural daylight before making your final choice.

How Do You Know If You Need 1B?

1B can be a good choice when your natural hair looks like a soft, natural black rather than a very deep jet black.

Look at your hair in daylight.

If your hair is:

• Very dark but not intensely black
• Black with a softer appearance
• Slightly brown-toned in certain lighting
• Naturally close to an off-black shade

then 1B may be a closer match than a very dark black.

But if your hair is noticeably brown, #2 may be more suitable.

When Should You Choose #2 Instead?

Choose #2 when your natural hair has a noticeable dark-brown tone.

This is especially important if you're trying to create a seamless blend rather than simply adding very dark extensions.

A #2 extension can work better when:

• Your natural hair looks dark brown in daylight
• Your ends are lighter than your roots
• Your hair has naturally warm brown tones
• You want the extensions to match the brown tones in your own hair

If your natural hair is black, moving to #2 can create too much contrast.

What If Your Hair Falls Between 1B and #2?

This is where colour matching becomes more difficult.

Your hair may not look like a single standard colour. It may sit somewhere between black and dark brown, especially if your hair has been exposed to sunlight or previous colouring.

If you’re not sure whether your natural hair falls between 1B and #2, we recommend ordering our Custom Colour Service. Our standard extensions come in natural black 1B, while any other colour requires a custom colour. 

If that natural colour isn't the match you're looking for, you can use the Colour Service to request a different colour for your extensions.

When Should You Use a Hair Extension Colour Service?

Our colour service becomes useful when the standard extension colour doesn't give you the match you want.

You may want to consider it if:

• Your natural hair is lighter than the available shade
• Your hair is darker than the natural extension colour
• You want a specific black or brown shade
• You want your extensions to match coloured natural hair
• Your hair has a unique tone that doesn't fit a standard shade
• You want highlights or a more customised colour

To All My Black Girls extensions sit nicely between 1B and #2, with a natural black shade across all our products. However, if you want a deeper or lighter colour, you can add the Colour Service to your order to get a custom shade made to suit your hair.

If you want any other colour, such as blonde, ombre, or another customised shade, the Colour Service is available to create a shade that better suits your hair.

1B vs #2: Which One Looks Darker?

1B is darker than #2.

The easiest comparison is:

1B → black/off-black
#2 → dark brown

If you're deciding between the two, don't choose based only on which one looks darker on your screen.

Instead, compare the shades against your natural hair in daylight.

If your hair looks black, start with 1B.

If your hair has obvious brown tones, #2 may be closer.

What If Your Natural Hair Is Jet Black?

If your natural hair is a very deep, solid black, a 1B extension may look slightly softer next to it.

This doesn't automatically mean the extension won't blend. The final appearance also depends on how much of your natural hair is left out and how the extensions are styled.

However, if you want an extremely close match to Colour 1 hair, a customised colour may be worth considering. 

What If Your Natural Hair Is Dark Brown?

If your hair is dark brown rather than black, #2 may be a more natural starting point than 1B.

Look at your hair in daylight rather than bathroom or bedroom lighting.

If you can clearly see brown tones throughout your natural hair, a blacker extension may look noticeably darker once installed.

How to Check Your Hair Colour Before Ordering

Before placing your order, use this simple check:

• Step 1: Look at your natural hair in daylight.
• Step 2: Check both your roots and ends.
• Step 3: Decide whether your hair looks black, soft black or dark brown.
• Step 4: Compare it with 1B and #2 rather than choosing the darkest shade automatically.
• Step 5: Order hair samples from us to get a real-life colour comparison with your natural hair. 
• Step 6: If neither shade looks right, consider a customised colour through the Colour Service. 

This approach gives you a much better starting point for matching your extensions.

Final Thoughts

Finding the right extension colour isn't about choosing the darkest shade available.

The difference between natural black, 1B and #2 can be subtle, but it becomes much more noticeable when the extensions are placed next to your natural hair.

As a simple guide:

• Natural black: deepest natural-looking black
• 1B: softer black or off-black
• #2: dark brown

If your hair looks naturally black but not intensely jet black, 1B hair colour can be a useful starting point. If your hair has visible brown tones, #2 may be closer.

And if the standard natural colour doesn't match your hair closely enough, the Colour Service gives you an option for a more customised match.

The goal is simple: match the extension to the hair you actually have, not just the colour name you think sounds closest.
