Does anything suck more than realizing your foundation is kinda… off? Like, you thought you were SLAYING the look, only to peep yourself in a mirror with better lighting and BAM—the dreaded line of demarcation. OOF. We’ve ALL been there. If you’ve ever noticed that your face looks way too yellow, orange, ashy (ouch), or just plain “wrong” even though you thought you’d nailed your shade, there’s a BIG chance the undertone is the issue.
Sooo, let’s break it down, because foundation undertones are basically the sneaky little detail that can make or break your entire face beat. And trust me, sis, you don’t wanna be out here dating someone with your foundation 2-tones off (or looking wild at brunch with the squad). Let’s get into it!
What Are Undertones? Like… For Real
Okay, so the thing is: when makeup brands talk about “undertones,” they’re talking about the color that comes from under your skin (duh). It’s not something you see outright unless you’re like, crazy good at spotting minute details on your skin (and if you are, kudos). It’s more about what colors naturally show through your skin, giving it an overall “tonal” feel.
Think of your undertone as the “vibe” of your skin color. Seriously—like, someone might look tan, but there’s an undertone there that makes them look either more golden or slightly red. Others might be pale, but their undertone might be blue-ish, making them look cooler or even ashy if not matched well. It’s all about finding the foundation that vibes with your skin’s natural mood.
If you get your undertone wrong, the finished look of the foundation might leave you lookin’ like:
- You’re wearing a mask (ew).
- You applied foundation in the dark.
- Your neck and face gave up on being friends.
None of those are the goal, am I right? 🙅♀️
Cool, Warm, and Neutral: What’s Your Vibe?
There are three main types of undertones: cool, warm, and neutral. Every foundation shade lies somewhere within these categories. So let’s figure out which one YOU are.
📉 Warm Undertones
Warm undertones come from golden, peachy, or yellow notes in your skin. It’s like you’ve got that summer glow all year round—even in winter, when you might be paler. If you have warm undertones, gold jewelry probably looks bomb on you, and your skin might tan easily instead of burning (yass, melanin queen).
Here’s how you can identify if you’ve got warm undertones:
- Your veins (lol, weird but true) on the underside of your wrist look GREEN.
- Gold jewelry is super flattering on you.
- Your skin starts to look ashy with cool-colored foundations.
Foundation shades to look out for: Honey 🍯, Golden 🏆, Toffee 🍬 (you get the vibe).
📶 Cool Undertones
You’re on the cool-toned side of life if your skin has pink, red, or blue-y/purple-y (is that even a word? Whatever, DRAMATIC) undertones. When people have cool undertones, they tend to POP in silver jewelry, and their skin can easily burn without sunscreen (ouch).
Signs you’ve got cool undertones:
- Paired with gold jewelry? Ehhh, not your best friend. But silver? OBSESSED.
- Your veins look more blue.
- When you wear super warm-toned foundation, you look kinda orange or too yellow.
Foundation shades for cool babes: Ivory ❄️, Rose 🌹, or Porcelain 🍼.
🔲 Neutral Undertones
Neutral undertones are the unicorns of the bunch. You don’t pull too much in either direction (lucky you), meaning neither pinks nor yellows take over your skin. Most people usually fall under warm or cool undertones, so if you’re neutral, CONGRATS—foundation matching is usually less of a hassle.
Signs you’re neutral:
- Both gold AND silver jewelry look cute on you (queen of flexing whatever accessories you want).
- Your veins? They’re uh… in-between? Not quite looking all the way green or blue, just somewhere smack dab in the middle.
- When you try on peach or pink blush, either can potentially suit you.
For neutral skin, look for shades like: Beige 🦋, Buff 👟, or Nude 🍦.
BUT WAIT, How Do You Know Your Undertone For Sure?
You’re probs reading this and thinking, “Suuuh?? How do I figure out which one is ME so I can quit buying the wrong foundation at Sephora every time?” I got you—let’s try out these easy tricks:
- Check Yo’ Veins Boo
Like I mentioned earlier, take a good look at your wrist veins. If they look greenish, you’re prolly warm-toned. If they’re more blue or purple, you’re cool-toned. Can’t tell? Good news real quick: chances are, YOU’RE NEUTRAL. - The White/Off-White Shirt Test
Hold both a white shirt and an off-white shirt next to your skin. If you shine in stark white, ding ding! You’ve got cool undertones. If you rock off-white better, then you’ve got warm undertones, babe. - Sun Goddess or Lobster Life?
Do you tan super easily? Then you might be warm-toned. Or do you burn after just getting a lil’ sun? Cool-toned life. -
Jewelry: Gold or Silver?
Like I mentioned up top (but it’s so important it gets its own spot here): if you look amazing in gold jewelry, it’s probably bc your skin is warm. Cool-toned skin rocks silver better.
Pro Tip: Above all, your own perception matters most. You know your skin more than anyone else. If foundations make you feel papery (yup, that’s a thing), it’s mostly bc of the wrong undertone.
Why Red is NOT the Move for Warm Undertones
Sis, let’s clear up a myth because somehow some people still believe it: if you are warm-toned, red-toned or pink-ish foundations… will NOT suit you! Despite what anyone says! Trust me, looking like a lobster after spending $$ on a $50 foundation ain’t it.
Mastering your undertone is basically the foundation of slaying any makeup look. Cool-toned gals and pink foundations just don’t mesh well. Same for warm tones mixing with red-based shades.
Popular Foundation Mistakes To STAY AWAY From 🚫
Listen UP 👏 because you do NOT want to commit these tragic foundation faux pas. They will mess up your whole makeup slay, and 2023 ain’t the year for mismatched looks.
1. Ignoring the Neck Match 🤦♀️
Checking your face alone isn’t enough. When testing foundation, always carry that action down! Blend it down to your neck to make sure your face and neck are doing a friendship duo and match completely. This way, you avoid ending up with floating head syndrome (trust me, it’s not the look you’re going for).
Girlie cheatsheet: Using a darker bronzer across your jawline could also balance this if needed.
2. Fixating ONLY on Face Swatches
Yes, yes—you’ve seen tutorials. But ONLY swatching on the side of your face? Rookie move. Instead, stretch that swatch love to places like your chest, neck, or jaw—areas where people can see your skin up close and personal. 🙏
3. Overcorrecting Undertones
Trying to manipulate your undertone might sound cool in theory, but you’re bound to mess it up (guilty). For example, if you TRY to make your cool-toned skin warm, your complexion could go orange or yellow very quick compared to neutral-toned babes.
Let’s Keep It Real: The Lighting. Changes. EVERYTHING.
Ooof let’s talk about one more annoying but important thing: lighting affects everything. I’ve seen people test their foundation by a dim bathroom light and it looks fineeeee. THEN they step outside… boom. Disaster! So here’s the scoop:
Always check in both indoor and outdoor lighting after applying, especially if you’ll be out during the day. You don’t want to be the one in group photos looking like you missed foundation matching class by a whole decade.
The Final Word
Undertones MATTTTEEERRRR. If you take away ANYTHING from this post, it’s this: the most bomb foundation doesn’t just stop at shade matching. The undertone match is just as important. It’s like finding the perfect relationship—you’re looking for one that COMPLETES your skin and makes you feel like a freakin’ 🦄 (without doing the absolute most).
And because you’re here reading this and actively trying to improve your makeup game, you’re def on the right track. Keep doing you, keep slaying those makeup looks, and let’s make mismatched foundation undertones a problem of the past.
P.S. Feel free to let me know if you need any help picking a good foundation brand that understands undertones—I got maaaad tips for that too. Keep glowing ✨
