How to Pick Glasses for Your Skin Undertone

Glasses are the only accessory that sits permanently on your face. A frame in the wrong temperature does the same thing a bad hair color does, except you put it on and take it off every day and never quite work out why some pairs photograph well and others don't.

The short answer: to pick glasses for your undertone, match the frame's temperature to your skin's temperature and the frame's depth to your own depth. Warm undertones look best in tortoise, honey, gold, copper, warm brown, and olive. Cool undertones look best in black, silver, gunmetal, plum, blue-grey, and clear frames with a cool cast. Neutral undertones can take a soft tortoise, a rose gold, or a matte brown-black. Then adjust the darkness of the frame to your natural contrast so it does not overpower your features. Below is how to run each of those three checks on yourself in about five minutes.

Why frames follow your undertone

Frames sit within two inches of your eyes and cheekbones, closer to your face than any garment ever gets. At that distance, the frame's color reflects onto your skin and mixes with it. A gold frame throws a faint warm cast across the top of your cheeks. A gunmetal frame throws a faint cool one. On the right skin that cast reads as warmth or clarity. On the wrong skin it reads as sallowness or as a slightly grey, tired look under the eyes.

The same principle governs jewelry, and most people already have an instinct for it: some of us look better in gold, some in silver. Frames are that decision made permanent and enlarged. If you already know from the gold or silver jewelry test which metal suits you, you already know roughly which half of the frame wall is yours.

The other half of the problem is shape, and shape is a separate question that has nothing to do with color. Face shape decides whether you want a round, rectangular, or aviator silhouette. Undertone decides what color that silhouette should be. Both matter, and opticians tend to only talk about the first one. Our skin tone analyzer guide covers the color half in depth, including how undertone and depth are read from a photograph.

Step 1: Find your undertone

Everything downstream depends on this, so it is worth doing properly rather than guessing. If you have never checked, the at-home undertone tests take about five minutes and cover four independent methods. The condensed version:

• Vein test. In natural daylight, look at the inside of your wrist. Green-leaning veins point warm. Blue or purple-leaning veins point cool. A mix points neutral.
• Jewelry test. Hold a gold item and a silver item near your jaw, one at a time. Whichever makes your skin look more even and less shadowed is your temperature.
• White paper test. Hold a sheet of plain white paper under your chin in daylight. Skin that looks yellow or peachy against it is warm. Skin that looks pink or slightly blue is cool. Skin that looks greenish is often olive, which can sit in either camp.
• Photo test. Take a selfie in indirect daylight with no filter and let the app read it. This bypasses the problem that most people's self-assessment is influenced by their tan, their current makeup, and the lighting in their bathroom.

If the tests disagree with each other, you are probably neutral undertoned, which is more common than the internet suggests and which opens up more of the frame wall rather than less. If you consistently read greenish, read our olive skin tone guide before you shop, because olive behaves differently from both warm and cool. For the underlying distinction, our piece on warm vs cool undertone explains what is actually happening in the skin.

Step 2: Match the frame material and color

If you are warm

Your skin has a golden, peachy, or honeyed cast, and gold jewelry suits you. Your frames should carry the same warmth.

• Acetate: classic tortoise, honey, amber, warm brown, camel, olive, warm ivory, terracotta.
• Metal: gold, brushed brass, copper, bronze, warm champagne.
• Skip: pure black, silver, gunmetal, icy clear, cool grey. These pull the yellow out of warm skin and make it read sallow rather than golden.

If you are cool

Your skin has a pink, rosy, or blue cast, and silver jewelry suits you.

• Acetate: black, blue-black, charcoal, plum, burgundy, navy, blue-grey, cool clear crystal.
• Metal: silver, gunmetal, steel, white gold, matte chrome.
• Skip: orange-based tortoise, honey, camel, bronze, and copper. Warm frames on cool skin tend to amplify redness around the nose and cheeks.

If you are neutral

You have flexibility, and the frames that work best sit in the middle of the temperature range rather than at either extreme.

• Acetate: soft brown-black, greyed tortoise, mushroom, taupe, muted rose, dusty green.
• Metal: rose gold, brushed nickel, matte pewter, two-tone frames.
• Skip: the loudest versions of either temperature. A high-saturation orange tortoise or an icy chrome will both look slightly borrowed.

Step 3: Set the frame depth to your contrast

Temperature tells you which family. Depth tells you how much frame you can carry, and this is the step almost everyone skips.

Your natural contrast is the gap between your hair, your eyes, and your skin. Someone with black hair and fair skin has high contrast. Someone with light brown hair, hazel eyes, and beige skin has low contrast. Our contrast level guide gives you a black and white photo test that settles it quickly.

• High contrast: you can wear a strong, dark, defined frame. A thick black acetate or a bold tortoise matches the drama already in your face rather than competing with it.
• Medium contrast: mid-weight frames in mid-depth colors. Classic tortoise, mid-brown, slate. Very heavy frames start to dominate.
• Low contrast: lighter, thinner, softer frames. Rimless, wire, light tortoise, translucent acetate, mushroom. A heavy black frame on low-contrast coloring becomes the first thing anyone sees, and the face behind it recedes.

This is the single most common frame mistake: buying a heavy black frame because it looked good on someone with completely different coloring. It is the same mechanism described in our piece on colors that wash you out, applied at close range.

Frame color chart by undertone

If deep skin is part of the picture, our guide to color analysis for deep skin tones covers the extra nuance, because depth and undertone are independent and deep skin spans the full warm to cool range.

Frame picks by color season

Once you know your color season, the frame answer narrows further, because season encodes temperature, depth, and clarity all at once.

• Winters take the sharpest frames of anyone: true black, blue-black, gunmetal, clear crystal, and a cool burgundy. Winter is the one group a heavy black frame genuinely belongs to.
• Summers take softer cool frames: blue-grey, slate, dusty plum, brushed silver, and a smoky translucent. Pure black usually overpowers Summer's muted contrast.
• Autumns take the richest warm frames: tortoise, espresso, amber, olive, and antique gold. This is tortoise shell's home season.
• Springs take clear warm frames at lighter depth: honey, coral-tinted acetate, warm clear, and polished gold. Very dark frames tend to weigh Spring coloring down.

Not sure which of the twelve is yours? The which season am I walk-through narrows it by hand, and the personal color analysis guide explains what each season means in practice.

Sunglasses, tints, and lens color

Lens tint follows the same temperature rule, with one extra wrinkle: the tint colors your whole face for anyone looking at you through the lens, and it colors the world for you.

• Warm undertones: brown, amber, bronze, and copper lenses. They enhance the golden cast in your skin and give the most natural-looking contrast outdoors.
• Cool undertones: grey, smoke, and blue-mirrored lenses. Grey is the most color-neutral tint available, which suits cool skin that does not want extra warmth pushed into it.
• Neutral undertones: both work. Green-grey lenses split the difference well.
• Gradient lenses are the low-contrast friendly option, because they keep the darkest part of the lens away from your cheeks.

A practical note on sunglasses: the frame is often much larger than a prescription frame, so the temperature effect is stronger, not weaker. If you have ever bought sunglasses that looked great in the store and never once looked right in a photo, temperature is the usual culprit. Store lighting is warm by design, which is exactly the problem our piece on how lighting changes your color read describes.

How to test frames in the store

1. Go to the window. Optical shop lighting is warm and flattering. Take the frames to daylight or a doorway before deciding anything.
2. Take a photo, not a mirror look. A mirror shows you what you expect. A front-facing photo shows you what other people see. Take one photo per frame and compare them side by side afterward.
3. Watch your under-eye area, not the frame. The right frame makes the shadows under your eyes look lighter. The wrong one deepens them. This is the fastest single tell.
4. Try one warm and one cool version of the same shape. Same silhouette, different temperature. The difference will be obvious in the photos and almost invisible in the mirror.
5. Bring your palette. If you already know your season, pull up your palette on your phone and hold it next to the frame. Frames that sit inside your palette will agree with everything else you own.

If you want to skip the guessing entirely, the app reads your undertone and depth from one selfie and gives you the palette to shop from. It is the same read described in what colors look good on me, applied to whatever you are shopping for that day.
