If you’ve ever found yourself looking at a hair colour swatch at the salon and felt a bit uncertain about whether it would actually look good on you, you’re definitely not alone. Figuring out a shade that really complements your skin’s undertone can seem like cracking a secret beauty code, and one wrong choice can mean the difference between a stunning glow-up and a look that just feels slightly off.
When you pick a colour that genuinely flatters your skin undertone, everything just clicks. Your complexion appears brighter, your features pop in the best way, and your overall vibe feels more effortless – like your natural glow has just been dialed up a notch.
In this guide, we’re diving into warm undertones – what undertones are, how to figure out if you have one, and the best hair colours to boost that golden warm undertone. From auburn to honey blonde, here’s your ultimate guide to shades that highlight your natural radiance.
What Is A Skin Undertone?
Your skin tone refers to the outer colour of your skin – whether it’s fair, medium, tan, or deep – and it can shift depending on sun exposure or your skincare habits. Your undertone, however, is the subtle shade that lies beneath your skin and remains constant regardless of how dark or light you become.
Think of it as the natural “temperature” of your skin. Some have a warm, golden glow, while others sport a cool, rosy hue, and some are right in the middle. Understanding your undertone is like having a personal colour guide – it assists you in choosing the most flattering shades for everything from makeup to clothes, and yes, even hair colour. There are 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 determine your undertone – just some careful observation and good lighting.
Begin by examining your veins – if they appear greenish, you probably have a warm undertone. If they look blue or purple, you’re likely cool. And if you’re unsure, you’re most likely neutral. Jewellery can also provide hints – gold usually enhances warm undertones, while silver is more flattering for cool ones.
You might also want to try the white shirt test – if your skin looks golden or sun-kissed against white, you have a warm undertone. If it appears rosy or pink, you’re cool. And if your skin has a slight greenish tint that doesn’t strongly lean in either direction, you could have an olive undertone, which is a blend of warm and neutral.
Once you’ve identified your undertone, you’ll begin to see how certain colours can really brighten your complexion – that’s the magic of aligning with 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. This means your complexion looks amazing with rich, sunlit shades. Think golden browns, coppers, and honey hues that make your skin glow instead of looking washed out.
Cool or ashy tones can sometimes take away from your warmth, so it’s better to go for colours with golden or red bases that boost your natural radiance. Here are some shades that are always a hit.
