If you’ve ever stared at a hair colour swatch at the salon and felt unsure whether it would actually suit you, you’re not alone. Finding a shade that actually complements your skin’s undertone can feel like decoding a secret beauty language, and one wrong guess can be the difference between a radiant glow-up and a look that just feels a little off.
When you choose a colour that truly flatters your skin undertone, everything falls into place. Your complexion looks brighter, your features stand out in the best way possible, and your overall look feels more effortless – like your natural glow just got turned up a notch.
In this guide, we’re focusing on warm undertones – what they are, how to tell if you have one, and the best hair colours to enhance that golden warmth. From auburn to honey blonde, here’s your go-to guide to shades that bring out your natural radiance.
What Is A Skin Undertone?
Your skin tone is the surface colour of your skin – fair, medium, tan, deep – and it can change with sun exposure or your skincare routine. Your undertone, on the other hand, is the subtle hue that sits beneath your skin and stays consistent no matter how tanned or pale you get.
Think of it as your skin’s natural “temperature.” Some people have a warm, golden glow, while others have a cool, rosy tint, and some fall right in between. Knowing your undertone is like having a personal colour compass – it helps you pick the most flattering shades for everything from makeup to clothing, and yes, even hair colour. It comes in four main categories:
- Warm – golden, yellow, or peachy
- Cool – pink, red, or bluish
- Olive – a mix of neutral and green/grey tones
- Neutral – a mix of warm and cool
How To Find Your Skin Undertone
You don’t need any fancy tools to figure out your undertone – just a bit of observation and good lighting.
Start with your veins – if they look greenish, you likely have a warm undertone. If they appear blue or purple, you’re cool. And if you can’t quite tell, you’re probably neutral. Jewellery can also be a clue – gold tends to flatter warm undertones, while silver suits cool ones.
You can also try the white shirt test: if your skin looks golden or sun-kissed against a white background, you’re warm. If it looks rosy or pink, you’re cool. And if your skin has a slightly greenish tint that doesn’t lean too far either way, you might have an olive undertone, which sits somewhere between warm and neutral.
Once you’ve figured out where you fall, you’ll start noticing how certain colours just make your complexion light up – that’s the power of matching your undertone.
Best Hair Colours For Warm Undertones
If your skin has a naturally golden, peachy, or yellow base, congratulations – you’ve got a warm undertone, and that means your complexion pairs beautifully with rich, sunlit shades. Think golden browns, coppers, and honey hues that make your skin look radiant rather than washed out.
Cool or ashy tones can sometimes dull your warmth, so it’s best to stick to colours with golden or red bases that enhance your natural glow. Here are a few shades that will never miss.

Smooth, decadent, and universally flattering, chocolate brown is the hair equivalent of a perfectly tailored blazer – it just works. The rich, golden undertones in this shade create a soft glow against warm skin, while the depth keeps things natural and sophisticated.
It’s perfect if you want something low-maintenance yet luxe, like you just casually woke up with “expensive brunette” energy. Bonus – it looks incredible in both sunlight and under café lighting (perfect for your Instagram selfies).

If you’re craving lighter hair, honey blonde is your golden ticket. The warm, buttery tones in this shade complement your skin’s warmth perfectly, adding a glow that feels soft and effortless – like good lighting, except it’s permanent.
It’s versatile too. Whether you want subtle highlights that catch the sun or a full head of luminous blonde, honey blonde adapts without washing you out.
On warm undertones, it enhances that natural golden glow, making your skin look radiant and healthy. It pairs beautifully with everything from cosy autumn sweaters to bold lipstick shades, giving you a look that’s polished without ever feeling overdone.
Warm Espresso

Deep, rich, and sophisticated, warm espresso is the go-to dark shade for anyone with warm undertones who wants something polished without looking flat. Unlike jet black or cool-toned browns, warm espresso has subtle golden or reddish undertones that harmonise with your skin’s natural warmth.
This means it enhances your complexion rather than creating a stark contrast that can make warm skin look dull. The result is hair that looks glossy, dimensional, and full of life – the kind of shade that feels effortlessly elegant while still flattering your natural glow. It’s perfect for anyone who loves a darker look but wants to keep their warmth front and centre.
Caramel

Sitting beautifully between blonde and brunette, caramel tones are the ultimate sunlit shade. The mix of golden and toffee hues enhances your skin’s natural warmth, giving your complexion a radiant, healthy glow.
On warm undertones, caramel works like a gentle spotlight, brightening your features without looking harsh or artificial. Whether you want soft balayage highlights, chunky face-framing pieces, or an all-over rich caramel, the colour adds depth and dimension to your hair while keeping it soft and luminous.
The overall effect is an effortless, sun-kissed warmth that feels natural, polished, and completely flattering – the kind of glow that turns heads without trying too hard.
Golden Copper

For the bold and the brave, golden copper combines the richness of red with the brightness of gold, creating a shade that literally glows.
On warm undertones, the golden flecks enhance your skin’s natural warmth, while the red tones add depth and vibrancy, giving your complexion a lively, radiant boost. It’s a shade that demands attention without feeling overpowering, perfect for anyone who wants their hair to make a statement while still flattering their natural colouring.
Golden copper also adds dimension and movement, catching the light in all the right ways, so whether it’s a full head of this fiery hue or subtle highlights, it brings energy, warmth, and a playful edge to your overall look.
