The vein test is only the beginning. Pros break down how to decode your undertone and why knowing it can change your whole beauty routine.
Let’s be honest: Figuring out whether your skin tone leans warm or cool sounds easy until you actually sit down to do it. Maybe you’ve turned your wrist toward the window trying to decide whether your veins look blue or green. Maybe you’ve held up gold hoops, then silver ones, waiting for one to make you glow. Or maybe you’ve stood in the Sephora aisle holding a foundation that looked like your perfect match in the bottle, only to watch it turn ashy or orange the moment it hit your skin.
If that sounds familiar, you’re not alone. Makeup artists say the popular shortcuts don’t always tell the full story, and finding your true undertone often takes a little more detective work.
Your Skin Tone and Undertone Are Two Different Things
Here’s where the confusion usually starts. Gabriella Elio, a makeup artist and the founder of Sweed Beauty, told InStyle that skin tone describes your surface depth, whether that’s fair, light, medium, tan or deep. That surface shade can change, especially after time in the sun. Your undertone is the color sitting beneath the surface, and it tends to stay consistent.
Elio also wants people to know that warm and cool aren’t the only options. Neutral and olive undertones exist too, which means not everyone fits neatly into one box.
Celebrity makeup artist Nydia Figueroa agrees. She describes undertones as a spectrum, noting that many people are neutral, with an even balance of warm and cool. Olive complexions add another twist, since they can lean warm, cool or neutral.
Why Knowing Your Undertone Is a Beauty Game Changer
Once you know your undertone, shopping gets a whole lot easier. The biggest payoff is a foundation that actually melts into your skin, but the benefits go well beyond your base. Your undertone can help guide your blush, lipstick, jewelry, hair color and even the colors in your closet. According to Elio, the right shades can brighten your complexion, make your eyes pop and pull your entire look together.
But don’t treat it like a set of rules you can never break. Elio sees undertone as a starting point, and she said reaching for a contrasting shade on purpose can sometimes create an even more striking look. Figueroa feels the same way, calling undertone helpful intel rather than a restriction. The takeaway? Understand the basics, then have fun with it.
What Warm and Cool Undertones Look Like
Warm undertones, Figueroa explained, carry hints of peach, yellow and gold. That glow shows up across every complexion. Beyoncé, Jennifer Lopez and Jessica Alba each have a different skin depth, but they share that signature golden warmth.
Cool undertones lean pink, red, rosy or blue, and they also appear across the full range of skin tones. Lupita Nyong’o, Dakota Johnson and Anne Hathaway all have different complexions, yet each carries that cooler cast beneath the surface.
Look Beyond Your Face
Figueroa has a key tip for foundation shopping: Don’t judge a shade by your face alone. Redness, discoloration, sun exposure and even your skin care can change how your facial skin looks. She checks the neck, chest and other visible areas so your complexion looks seamless from head to toe. The goal, she said, isn’t to change your natural undertone but to find a shade that works in harmony with it.
How to Find Your Undertone at Home
Ready to play detective? Start in natural light and check the veins on your inner wrist. Blue or purple veins usually point to cool undertones, while green veins suggest warm ones. Then compare how gold and silver jewelry look against your skin. Finally, swatch one warm-leaning and one cool-leaning foundation along your jawline and see which blends most naturally into your face and neck.
Since redness and sun exposure can throw off the results, look for a pattern across several tests instead of relying on just one. Still stuck? A makeup artist or beauty professional can assess your skin in person and give you an expert second opinion.
At the end of the day, knowing your undertone isn’t about limiting yourself. It’s about walking into every beauty decision with a little more confidence.
