Finding the perfect lipstick is more than just picking a color you like in the tube; it is a strategic process of matching pigments to your biological undertones. A shade that looks like a vibrant ruby on one person may appear as a dull brick on another due to the way light interacts with the skin’s surface.
To achieve a professional look, you must first identify your technical skin profile. This guide provides a step-by-step breakdown of how to identify your undertones and select specific shades that enhance your natural features.

Step 1: Identify Your Biological Undertone
While your skin tone (fair, medium, deep) can change with sun exposure, your undertone remains constant. According to makeup artist Taylor Weiss via Cosmopolitan, your undertone is the subtle hue beneath the surface that influences how colors interact with your complexion [1].
Use these three diagnostic tests to find yours:
- The Vein Test: Look at the veins on your wrist in natural sunlight. If they appear blue or purple, you have cool undertones. If they appear green, you have warm undertones. If you cannot distinguish between the two, you are likely neutral [2].
- The Jewelry Test: Determine which metal makes your skin look “vibrant” rather than “washed out.” Silver and platinum typically flatter cool undertones, while gold enhances warm undertones. Neutral tones can wear both equally well.
- The White Paper Test: Hold a sheet of stark white paper next to your clean face. If your skin looks pink or rosy by comparison, you are cool. If it looks yellow or sallow, you are warm [3].
Identifying your undertone is the foundation of all color cosmetics. Just as you would choose the right foundation for your skin tone, your lipstick must align with these base pigments to look natural.
Your skin tone refers to the surface color (like fair, medium, or deep) and can change based on sun exposure. Your undertone is the subtle hue beneath the surface, such as cool, warm, or neutral, and remains constant throughout your life.
If you look at the veins on your wrist and cannot clearly distinguish between blue, purple, or green, or if they appear to be a mix of both, you likely have a neutral undertone. People with neutral undertones often find that both silver and gold jewelry look equally flattering on them.
Yes, identifying your biological undertone is the foundation for all color cosmetics. Just as with lipstick, matching your foundation to your cool, warm, or neutral base pigments ensures a natural look rather than a mask-like appearance.
Step 2: Selecting Shades Based on Skin Depth
Once you know your undertone, you can narrow down the vast array of lipsticks into “safe” and “bold” categories based on the depth of your skin.
Fair and Light Skin Tones
Light skin often has cool or neutral bases. The goal here is to add color without overwhelming the face.
Cool Undertones: Opt for soft pinks, berry shades, or “blue-based” reds (like a classic cherry). These cut through paleness to illuminate the face [2].
Warm Undertones: Look for peachy nudes, corals, and pale orangey-pinks.
Avoid: Beige-heavy nudes, which can make fair skin look sickly or “washed out.”
Medium and Olive Skin Tones
Medium skin is highly versatile, but olive skin, in particular, carries green or neutral undertones that require specific pigments [1].
Cool/Neutral: Mauves and rosy pinks are highly effective for daily wear.
Warm/Olive: Earthy tones like terracotta, brick red, and metallic copper complement the golden or olive pigments in the skin.
Pro Tip: If you have olive skin, Hindustan Times suggests cinnamon and caramel browns to blend seamlessly with your natural richness [2].
Deep and Dark Skin Tones
Deep complexions handle high-saturation pigments and bold contrasts better than any other category [4].
Cool Undertones: Deep plums, blackberries, and blue-toned reds (think dark ruby) create a sophisticated, regal look.
Warm Undertones: Vibrant oranges, fiery fuchsias, and chocolate browns with red bases (like espresso) look radiant.
Neutral: Rich, true reds and deep berry-mauves.
For a cohesive appearance, remember that your lip color is part of a larger system. To see how this fits into your overall routine, see our guide on how to select the right makeup for your skin type.
Olive skin often carries green or neutral undertones that pair beautifully with earthy pigments. Professional stylists recommend terracotta, brick red, and metallic copper, as well as cinnamon and caramel browns to complement the skin’s natural richness.
Beige nudes often lack the necessary pigment to contrast with pale complexions, which can lead to a “washed out” or sickly appearance. Instead, those with fair skin should look for peachy nudes or soft pinks to add healthy color to the face.
Absolutely! Deep complexions handle high-saturation pigments better than any other skin depth. Vibrant oranges, fiery fuchsias, and deep berries create a striking and sophisticated contrast against darker skin tones.
Step 3: Understanding Lipstick “Bases”
Lipstick shades are categorized by their base color, which determines whether they are “warm” or “cool.”
Blue-Base: These are “cool” reds and pinks. They often make teeth look whiter because the blue tint counters yellow stains.
Orange/Yellow-Base: These are “warm” reds, corals, and nudes. They emphasize the golden glow of the skin but can occasionally highlight yellow tones in teeth [5].
To make your teeth appear whiter, choose “blue-based” lipsticks, which are typically found in cool reds and berry shades. The blue tint in these pigments helps to visually neutralize yellow stains on the teeth.
An orange-based red is a warm shade that emphasizes the golden glow of the skin, while a blue-based red is a cool shade that creates a more classic, high-contrast look. Choosing between them depends on whether your skin’s biological undertone is warm or cool.
Real-World Testing and Expert Advice
Professional makeup artists recommend “swatching” in natural light whenever possible. Store lighting is often fluorescent or overly warm, which can distort the actual pigment of the product [1].
Community discussions on platforms like Reddit (r/MakeupAddiction) suggest that if you are struggling with a “nude” shade, you should look at the natural color of your inner lip and go one or two shades darker. This ensures the “nude” look has enough depth to prevent your lips from disappearing into your face [3].
Fingertips are a better swatching location because the skin there more closely mimics the natural red and pink tones of your actual lips. This provides a more accurate representation of how the color will look once applied to your face.
A great expert tip is to look at the color of your inner lip and select a shade that is one or two tones darker. This ensures the nude shade has enough depth to prevent your lips from disappearing into your complexion.
Store lighting is often fluorescent or artificial, which can distort the actual pigment of the product. Always try to view a swatch under a natural light source before purchasing to see the true color profile.
Summary of Key Takeaways
- Determine Undertones First: Use the vein, jewelry, or paper tests to find if you are cool, warm, or neutral.
- Match Base Pigments: Cool skin needs blue or purple-based lipsticks; warm skin needs orange or yellow-based lipsticks.
- Fair Skin: Focus on soft pinks and cherry reds; avoid beige nudes.
- Medium/Olive Skin: Use mauves, terracotta, and berry shades.
- Deep Skin: Go for high-saturation pigments like plum, espresso, and bright tangerine.
- Whiter Teeth: Choose blue-based reds to visually neutralize yellow tones.
Action Plan
- Perform the Vein Test today in natural sunlight.
- Clean out your current collection and identify which shades “clash” with your newly discovered undertone.
- When shopping, swatch the product on your fingertip rather than your wrist, as fingertips more closely mimic the natural red/pink tones of your lips.
- Always check the swatch under a natural light source before purchasing.
The perfect lipstick is the one that makes you feel confident. While these rules provide a scientific baseline for color theory, makeup remains a form of self-expression—if you love a shade that “breaks the rules,” wear it with confidence.
| Skin Depth | Cool Undertone | Warm Undertone |
|---|---|---|
| Fair | Soft Pinks, Berry, Cherry Red | Peachy Nudes, Corals |
| Medium/Olive | Mauves, Rosy Pinks | Terracotta, Brick Red, Caramel |
| Deep/Dark | Plums, Dark Ruby, Blackberry | Fiery Fuchsia, Espresso, Tangerine |
The three standard diagnostic tests are the Vein Test (checking for blue vs. green veins), the Jewelry Test (checking if silver or gold looks better), and the White Paper Test (checking for pink vs. yellow hues against a sheet of paper).
While color theory provides a scientific baseline for what is most flattering, makeup is ultimately a form of self-expression. If a specific shade makes you feel confident and happy, you should wear it regardless of the traditional rules.
