Finding your true cool undertone is a game-changer for your personal care routine. It’s the secret to choosing makeup that makes your skin glow, hair color that looks natural and vibrant, and clothing that makes you feel confident and put-together. Forget the guesswork and endless product returns. This guide will walk you through a simple, five-step process to pinpoint your cool undertone with accuracy and confidence.
Step 1: The Vein Check – A Quick and Easy First Look
The first and most accessible way to start your undertone investigation is by examining the veins on your wrist. This step is a reliable indicator and a great starting point, but it’s not the entire picture. You need to do this correctly to get an accurate read.
How to do it:
- Find the right lighting: Go to a window with natural daylight. Fluorescent lighting, bathroom lights, or even soft yellow lamps can distort colors and give you a false reading. Natural light is your best friend here.
-
Expose your wrist: Hold your wrist up to the light, palm facing you. Gently turn your hand back and forth to see the veins just beneath the skin.
-
Observe the color: Are your veins predominantly blue, purple, or a mix of both? This is the key. Cool undertones often have veins that appear blue or purple. If your veins look greenish, you likely have a warm undertone. If you see a mix of both blue/purple and green, you might have a neutral undertone, but for this guide, we’re focusing on the clear-cut cool signs.
Concrete Example:
Imagine you are standing by a sunlit window. You hold out your wrist and notice that the network of veins looks distinctly like the color of a royal blue ballpoint pen. There are no hints of green. This is a very strong initial signal that you have a cool undertone. If you see both purple and blue, the signal is even stronger.
Step 2: The Jewelry Test – Silver or Gold?
The type of jewelry that naturally complements your skin can provide another powerful clue about your undertone. This test is all about which metal makes your skin look more radiant, not which one you personally prefer.
How to do it:
- Gather your metals: You need both a piece of pure silver (or platinum) jewelry and a piece of pure gold jewelry. A simple earring, bracelet, or ring will suffice. The size doesn’t matter, just the color of the metal.
-
Try on the silver: Put on the silver piece. Look at your skin next to the silver. Does your skin look more vibrant, healthier, and brighter? Does the silver seem to blend seamlessly with your skin tone without looking harsh?
-
Try on the gold: Now, swap it out for the gold piece. Does the gold look a bit overpowering, even “sitter-on-top-of-the-skin” or does it make your skin look a little sallow?
-
Compare the results: People with cool undertones typically find that silver and platinum jewelry enhance their skin, making it look fresh and luminous. Gold jewelry, on the other hand, can sometimes make their skin appear a bit dull or ruddy.
Concrete Example:
You put on a simple silver chain. When you look in the mirror, your skin, especially your neck and chest area, seems to have a natural glow. The silver looks elegant and harmonious. Then, you put on a gold chain. While it’s a beautiful piece, it seems to sit on your skin rather than complement it. Your skin might even look a little flushed or less clear in contrast. This is a clear indicator that your skin’s natural tones are better served by the coolness of silver.
Step 3: The Sun Reaction – A Clue from the Elements
How your skin reacts to sun exposure is a strong biological indicator of your undertone. This test requires a bit of memory or a quick check after your next day outdoors.
How to do it:
- Recall or observe: Think back to the last time you spent an extended period in the sun without SPF (not recommended, but useful for this test). Did you typically burn easily, turning a shade of red or pink before you got a tan? Or did you tan easily without much burning?
-
Connect the dots: Individuals with cool undertones often have less melanin that is conducive to tanning. They tend to burn or turn red/pink first. While they might get a light tan eventually, the initial reaction is usually a burn. People with warm undertones, however, tend to tan more easily and often achieve a golden-brown color without the painful, initial burn.
-
Look for freckles: Another sun-related sign is the type of freckles you might develop. If your freckles tend to be reddish or pinkish in color, it’s another signal pointing to a cool undertone. Golden or yellowish-brown freckles are more common in people with warm undertones.
Concrete Example:
You remember a beach trip from last summer. While your friend, who has a warmer undertone, quickly developed a beautiful bronze tan, you spent the first two days turning a shade of lobster red. After a week, you eventually got a slight, pale tan, but the initial redness was undeniable. This classic “burn-and-then-light-tan” reaction is a hallmark of a cool undertone.
Step 4: The White and Off-White Test – A Look at Contrast
This test is a classic and effective way to see how colors interact with your skin. The goal is to see which shade of white makes your skin look healthier and more vibrant.
How to do it:
- Find the right fabrics: Get two pieces of clothing or fabric: one that is a pure, bright white, and another that is a creamy, off-white or ivory color. A simple t-shirt or a piece of cloth will work perfectly.
-
Drape the white: Drape the pure white fabric around your neck and shoulders, close to your face. Look at your reflection in a mirror under natural light. Does your skin look fresh, bright, and clear? Or does the white look too stark and maybe even a little draining?
-
Drape the off-white: Now, swap it out for the creamy off-white fabric. Does the off-white make your skin look a bit sallow or washed out? Does it highlight any redness in your skin?
-
Analyze the results: People with cool undertones typically look amazing in pure white. It complements their skin and makes them look crisp and vibrant. Off-white or ivory, with its yellow undertones, can often make cool-toned skin look a bit dull or sallow. The reverse is true for warm undertones.
Concrete Example:
You put on a pure white t-shirt. The color makes your skin look even and clear, and your eyes seem to pop. There’s a certain harmony between the stark white and your skin. Then, you try on a creamy ivory sweater. Suddenly, your skin looks a little less bright, and you notice some subtle redness in your cheeks that the ivory seems to highlight. The pure white is clearly the more flattering choice, a strong sign that you have a cool undertone.
Step 5: The Foundation and Lipstick Test – Your Final Confirmation
This final step is the most practical because it directly applies to your product choices. By trying on a few specific shades, you can get a final, conclusive answer.
How to do it:
- Head to a store with testers: Visit a makeup store or counter with good natural lighting and a wide range of foundation and lipstick testers.
-
Test a cool-toned foundation: Swatch a foundation that is explicitly labeled for cool or pink undertones. A common sign is the letter “C” in the shade name (e.g., C20, Cool Beige). Swatch it on your jawline, blending it down your neck. The correct shade will disappear into your skin, seamlessly blending away. If it looks natural and not ashy or orange, you’re on the right track.
-
Test a warm-toned foundation: Next, try a foundation with a warm or yellow undertone, often labeled with a “W” (e.g., W30, Warm Beige). Swatch it on the other side of your jawline. If it looks a little orange, sallow, or too yellow, it’s a clear miss. The contrast will be obvious.
-
Apply a cool-toned lipstick: Now, for the lipstick. Choose a true red with a blue base (not orange-red) or a berry pink. Apply it and see how it looks. Does it make your skin look brighter and your teeth whiter? Does it feel like a natural extension of your face?
-
Apply a warm-toned lipstick: Next, try a lipstick with a warmer base, like a coral or a peach. Does it look a bit off, maybe a bit jarring, or does it make your skin look sallow? Cool-toned individuals often find that warm, peachy lip colors don’t do their complexion justice.
Concrete Example:
At the makeup counter, you apply a cool-toned foundation (labeled C15) to one side of your face. It melts right in, and your skin looks clear and even. The other side, with a warm-toned foundation (W15), looks a bit peachy and doesn’t blend as well. Next, you try a blue-based lipstick and notice how it instantly brightens your entire face. A coral lipstick, however, seems to wash you out and makes your skin look a bit tired. This confirms that your skin thrives with cool-toned products.
