If you want to conceal grays or add subtle depth, 4N hair color is a gentle, neutral dark brown that offers you a natural look. You won’t get brassy or ashy tones since 4N maintains its balance, unlike some colors that pull excessively warm or cold. It’s a deep, rich brown that complements almost everyone.
We’ll cover all you need to know in this guide, including how 4N looks, who it works best for, how to apply it, and how to maintain its freshness. We’ll also discuss some of our favorite products, such as Garnier Nutrisse and Clairol Nice’n Easy Perfect 10. You’ll discover all the advice you need to look great in this shade, regardless of your level of experience with DIY hair color.
The dark brown shade 4N, which belongs to the level 4 hair color family, is rich and realistic-looking. It doesn’t pull too heated (reddish) or too chilly (ashy), as the letter “N” stands for neutral. Instead, it’s a realistic brown that is well-balanced and mimics the kind of deep, natural hair you’d see in real life.
Hair colors are labeled on a scale from 1 (black) to 10 (lightest blonde). So, 4N is a level 4—dark brown—with neutral undertones.
4.0 = Just plain dark brown (no strong undertones specified).
4NN = Sometimes means extra neutral or deeper richness.
4N = The sweet spot—no brassiness, no ashiness, just a soft, natural brown.
It’s become a go-to shade because it’s:
✅ Low-maintenance – No weird warm or cool tones popping up over time.
✅ Flattering – Works on most skin tones without looking unnatural.
✅ Versatile – Great for full gray coverage or just enhancing natural color.
No wonder it’s a favorite for anyone who wants a deep brown that stays looking fresh and real!
The fantastic thing about 4N is that it’s a huge hit with everyone! You’ll probably look fantastic in this hue because it complements so many different complexion tones. Still unsure? Let’s dissect it:
✔ Cool undertones (pink or blue-ish hues)?
4N will balance you out perfectly—no clash, just a gorgeous, natural look.
✔ Warm undertones (golden or peachy)?
No worries! 4N keeps things neutral, so you won’t end up with brassy red or orange tones.
✔ Neutral undertones?
Lucky you—this shade will blend right in, giving you rich, soft brown hair that just works.
🔹 Great gray coverage
Tired of those stubborn silvers? 4N covers them smoothly without looking fake or harsh.
🔹 A natural-looking dark brown
Not too flat, not too bold—just a healthy, dimensional brown that looks like you were born with it.
🔹 Low-maintenance color
Who has time for constant touch-ups? 4N stays fresh longer, so you can relax between salon visits.
Basically, if you want a foolproof brown that flatters and lasts, 4N is your new best friend.
Are you prepared to look stunning in that shade of dark brown? Here’s how to achieve salon-quality results at home without the hassle, whether you’re using Clairol Nice’n Easy 4N or another brand.
Before you dive in, test a small section of dye on your skin to rule out any allergic reactions. Better safe than itchy!
Grab your dye kit and mix the color cream with the developer just like the instructions say. If you’re using something like Clairol Perfect 10, they’ve done the measuring for you—easy peasy.
Put on some gloves (believe me, you don’t want your hands to get dyed) and begin using a brush or comb to apply the dye. Make sure every strand receives some love as you work from the beginning to the end. No one wants patchwork color, which is what missing areas are.
Set a timer for the recommended processing time—usually around 10 minutes for Clairol Perfect 10. Don’t try to “eyeball” it; follow the box directions for the best results.
When time’s up, rinse with lukewarm water (hot water fades color faster!) and use the conditioner that comes with your kit. This locks in moisture and keeps your color looking fresh.
Pro Tip: Be extra careful around your hairline—use Vaseline or a thick moisturizer as a barrier to prevent dye stains on your skin.
And voilà! You’ve just nailed a gorgeous, even 4N color all by yourself. Now go show off that rich, natural brown!

4N is a neutral dark brown (level 4 on the color scale). The “N” means it doesn’t pull warm (red/gold) or cool (ashy)—just a pure, natural-looking brown. Perfect if you want:
✔ Rich, even color
✔ No brassiness or dullness over time
✔ Great gray coverage without looking fake
4 is darker! Here’s the breakdown:
Level 4 = Deep, dark brown (think espresso)
Level 5 = Medium brown (like milk chocolate)
The higher the number, the lighter the shade.
Both are dark brown, but here’s the key difference:
4N = Neutral brown (balanced tone)
4NN = Extra pigment for tough gray coverage (may appear slightly darker)
👉 If you’ve got stubborn grays, 4NN is your best bet. Otherwise, 4N gives that perfect natural brown.
Pro Tip: Always do a strand test first—colors can look different on everyone!
