Undertone Test, Made Easy: Find Your Skin's True Match

Have you ever tried a skin undertone test? If you've looked one up or fallen down the TikTok undertone rabbit hole, you're probably curious what's actually going on under your skin. An undertone quiz gives you good information, and it's also the fastest route to your Cream Concealer shade.

In the video below, we walk through three quick ways to find your undertone at home.

Read on for our fail-proof undertone test, plus a guide to what undertones actually are.

Skin Undertone Test: Understanding Different Skin Undertones

If you've never taken a skin undertone test and aren't sure of yours, let's start with the basics.

Undertones are the hues beneath your skin's surface that change how colors look on you. It's worth knowing that your skin's undertone is different from its tone (the color of your skin's surface). There are three undertones: warm, cool and neutral.

Even the fairest skin can have warm undertones, and deeper skin can have cool ones. That's why matching a Cream Concealer can feel fiddly. A shade can be the right depth and still sit oddly, because it's fighting the hue just under the surface.

Here's how the three break down:

  • Cool undertones have a pink, red or blue cast. If your veins look bluish, or your skin looks better against silver jewelry, you're probably cool.
  • Warm undertones have a yellow, golden or peachy cast. Greenish veins and gold jewelry point warm.
  • Neutral undertones sit between the two. Your veins aren't clearly blue or green, and both metals look fine on you.

Subtl protip: your preference matters more than what any undertone test tells you. Makeup is supposed to be fun. Wear the thing you like.

Skin Undertone Test: Common Undertone Myths Debunked

A graphic separating three common undertone myths from the facts that correct them

There are a lot of undertone myths out there. Here are three worth clearing up:

  1. Myth: "if you tan easily, your skin must be warm." Fact: tanning ability doesn't determine undertone. It's about the hue underneath, not how your skin reacts to sun.
  2. Myth: "undertone and skin tone are the same thing." Fact: undertone is the hue beneath the surface. Skin tone is the surface color.
  3. Myth: "your undertone can change." Fact: your undertone stays put for life. Your skin tone shifts with sun exposure and other factors.

Undertone Test: Matching Your Cream Concealer Shade

Here's the part most shade guides make harder than it needs to be. You don't have to decode product names, because our shade codes already tell you the undertone.

Every Subtl Cream Concealer shade ends in a letter:

  • C is cool. 001C, 002C, 005C, 009C, 012C, 015C, 020C
  • N is neutral. 003N, 004N, 007N, 014N, 019N, 021N
  • W is warm. 006W, 008W, 010W, 013W, 016W, 017W

The number in front is depth, running light to deep. So 002C is a fair cool shade, 004N is a light neutral, and 010W is a medium warm one.

Once you know your undertone from the test above, you're looking for the letter. Then pick your depth.

Undertone Test FAQs

How do I know if I have a cool, warm or neutral undertone?

Check three things: your veins, your jewelry, and your skin against white paper. Bluish veins and silver jewelry point cool. Greenish veins and gold jewelry point warm. If neither is obvious and both metals suit you, you are likely neutral. The nine-question test on this page walks through the rest.

What is the difference between skin tone and undertone?

Skin tone is the color of your skin's surface. Undertone is the hue sitting underneath it. The two move independently, which is why two people with the same depth of skin can need different shades.

Can my skin undertone change over time?

No. Your undertone stays the same for life. Your skin tone shifts with sun exposure and other factors, but the hue underneath does not.

Does tanning easily mean I have a warm undertone?

No. Tanning ability does not determine undertone. Undertone is about the hue beneath your skin's surface, not how your skin reacts to the sun.

What do the letters in Subtl Beauty concealer shade codes mean?

The letter at the end of every shade code is the undertone. C is cool, N is neutral, W is warm. The number in front is depth, running light to deep. So 002C is a fair cool shade and 010W is a medium warm one.

What should I do if I am between two concealer shades?

Take the Subtl Beauty quiz. It accounts for the shades you already wear and narrows the choice down for you.
