How to Find Your Skin Undertone at Home

Skin Tone vs Skin Undertone: What’s the Difference?

Before diving into the tests, it is essential to distinguish between two concepts that are frequently confused: surface skin tone and underlying skin undertone. Your surface skin tone is the shade you see in the mirror at first glance—ranging from fair and medium to deep. Surface tone naturally fluctuates throughout the year due to sun exposure, skincare routines, or temporary redness, breakouts and flushing.

Conversely, your skin undertone is a permanent, subtle shade beneath the epidermis. Determined by genetics and melanin distribution in the deeper layers, it remains unchanged throughout your lifetime. Whether you are pale in the depths of winter or sporting a deep summer tan, your undertone stays exactly the same. Undertones fall into three main categories: warm (golden, yellow or peachy hues), cool (pink, red or bluish hints), and neutral (a balanced mix of warm and cool pigments).

In addition to these three core groups, there is also an olive undertone, which blends golden nuances with greenish, muted grey tones. Those with olive skin often find that standard warm foundations look too orange, while cool foundations appear overly pink. Learning to recognise these subtle nuances makes matching your wardrobe and makeup seamlessly intuitive.

1. The Wrist Vein Test

One of the quickest and most reliable methods to assess your undertone is inspecting the veins on the inside of your wrist or forearm. For accurate results, always carry out this test under direct, natural daylight—such as beside a north-facing window, away from harsh direct sunlight. Artificial yellow or fluorescent lighting can significantly distort colours and lead to a false reading.

Cleanse your wrist, roll up your sleeves, and examine the veins visible just beneath your skin:

• Blue or purple veins: If your veins appear distinctly blue, indigo or violet, you have a cool undertone. Your skin will look most radiant in cool-toned clothing, blue-based lipsticks and silver jewellery.
• Green or olive veins: If your veins look greenish or olive, your skin’s natural yellow pigment is filtering the blue light from your veins, making them appear green. This is a clear indicator of a warm undertone.
• A mix of both: If you see a combination of blue and green veins, or struggle to tell because they blend seamlessly into your skin tone, you likely have a neutral undertone that shares traits of both groups.

2. The Jewellery Test

Jewellery worn near the face—such as necklaces, earrings or hair clips—acts as a natural reflector that can either illuminate your features or accentuate shadows and dark circles. For this test, grab a piece of pure silver (or white gold/platinum) and a piece of yellow gold (or copper). Ensure your face is clean, sweep your hair back, and stand in front of a mirror in natural light.

Always use simple, plain pieces without brightly coloured gemstones for the jewellery test, as tinted reflections can warp your perception.

Hold the silver piece against your jawline and neck, then swap it for the gold. If silver makes your skin look vibrant, fresh and awake, while yellow gold leaves you looking sallow, your undertone is cool. If gold enhances your natural radiance and silver leaves you looking washed out, you belong in the warm category. If both metals look equally flattering, you are blessed with a versatile neutral undertone.

3. The White Paper or Fabric Test

Pure white acts as a neutral canvas that cancels out ambient background reflections. For this test, you will need a sheet of crisp, bright white printer paper (or a pure white cotton top) alongside an off-white, cream or ivory fabric. Stand before a mirror in natural daylight, holding the bright white material directly under your chin.

If your skin looks rosy, fresh or distinctly pinkish beside the pure white paper, you have a cool undertone. If your skin appears yellowish, dull or washed out against pure white, but suddenly glows when you hold up the warmer cream fabric, your undertone is warm. Neutral undertones suit both options comfortably. Once you master these nuances, building a flattering personal colour palette becomes second nature.

4. The Sun Reaction Test

How your skin behaves during your initial days in the sun serves as an excellent supporting indicator. Although this reaction is also influenced by surface melanin levels, your past tanning experiences offer clear clues that validate your other test results.

People with cool undertones typically burn easily or flush red in the sun, tanning very slowly. On the flip side, those with warm undertones tend to tan easily without burning, developing a golden-bronze glow effortlessly. Neutral undertones might burn slightly at first, but quickly transition into a rich tan. Understanding this trait simplifies selecting the right foundation for your undertone for both summer and winter.

Common Mistakes When Finding Your Undertone

Determining your undertone at home can lead to skewed results if performed under poor conditions or influenced by external factors. The most frequent pitfall is testing under artificial indoor light, which adds unwanted yellow or blue casts to your skin and masks your true undertone.

• Testing with makeup or tinted moisturiser: Even the sheerest BB cream or concealer will obscure your natural pigment. Always carry out tests on thoroughly cleansed, bare skin.
• Mistaking surface redness for a cool undertone: Rosacea, acne or skin sensitivity can cause surface redness on the cheeks, leading many warm-toned individuals to misdiagnose as cool. Always evaluate the skin on your neck, chest or inner wrist.
• Relying on a single test: Only draw a final conclusion when at least three different home tests yield consistent results.

If you notice your foundation shifting shade throughout the day, explore why your foundation looks orange or grey to prevent shade mismatched bases and ensure a flawless finish.
