Gold suits warm undertones; silver suits cool. To test yours: hold a piece of yellow gold and a piece of silver against your face or inner wrist in natural light — whichever metal makes your skin look brighter and more even reveals your undertone. If both look good, you're neutral. The whole test takes about 30 seconds.
The jewelry test works because metals cast a subtle color reflection that either harmonizes with your skin's undertone or clashes with it. A warm, golden reflection complements warm-undertoned skin; a cool, blue-white reflection flatters cool-undertoned skin. Here is the step-by-step method:
Judge by effect on skin, not personal preference. Many people have jewelry they love that doesn't technically flatter them. The test asks: which metal makes your skin look better — not which piece you like wearing.
If gold and silver both flatter your skin with no clear winner, you have a neutral undertone — a balance of warm and cool where neither dominates. Neutral is not a lack of undertone; it is its own distinct reading. Most neutral-undertoned people are either neutral-warm (a slight golden lean) or neutral-cool (a slight pinkish lean), which a full 12-season color analysis will distinguish.
Neutral undertones are associated with the "true" seasons in the Sci·ART 12-season system — True Spring, True Summer, True Autumn, True Winter — where the undertone is balanced enough that chroma and value drive season placement more than hue does. See the best colors for neutral undertones.
Olive undertone is a green-grey cast that sits above the warm/cool axis and can appear over fair, medium, or deep skin. If you are olive, the jewelry test often produces a third outcome: neither metal looks quite right. Bright silver can look harsh and cold; yellow gold can look too heavy or oversaturated. The metal that olive undertones typically find most harmonious is muted or antique gold — a slightly duller, more greenish-yellow tone rather than bright polished yellow gold.
Olive is common among people of Mediterranean, Middle Eastern, South Asian, Southeast Asian, and Latin American heritage, but it is not exclusive to any background. It spans every Fitzpatrick depth.
Undertone determines the broad metal category; your specific color season refines which shade within that category looks most harmonious.
| Season group | Undertone | Best metal | Notes |
|---|---|---|---|
| Spring (Bright, Light, True) | Warm | Yellow gold, rose gold | Clear, bright warm metals; avoid antique or very matte finishes |
| Summer (Light, True, Soft) | Cool | Silver, platinum, white gold | Soft metals work best; avoid high-polish yellow gold |
| Autumn (Soft, True, Deep) | Warm | Antique gold, bronze, copper | Muted, earthy metals; polished bright gold can read as too cool |
| Winter (Deep, True, Bright) | Cool | High-polish silver, platinum | High contrast cool metals; avoid warm or matte finishes |
Bright vs muted matters. Two people can both be warm undertone — one a Bright Spring who suits high-polish gold, and another a Soft Autumn who suits antique bronze. Undertone places you in the warm/cool family; chroma (your color season's clarity) determines how bright or muted the metal should be.
Mixed-metal jewelry (pieces that combine gold and silver) is most naturally flattering on neutral undertones, who hold the warm-cool balance in their own skin. But season-aware styling extends this further:
The jewelry test is one of the fastest undertone signals, but it reads only one axis. Undertone is just the first of three dimensions in the Sci·ART 12-season system — undertone (hue), value (depth from light to deep), and chroma (clarity from bright to muted) together determine your season and your full palette.
Tonebook reads all three axes from a single selfie, corrects for ambient light to isolate true undertone, and places you in one of the 12 seasons with a confidence label and a runner-up season. Built to read accurately across Fitzpatrick I–VI — so deep, olive, and fair skin are all analyzed on equal terms.
One selfie. Tonebook reads your undertone, value, and chroma to place you in the 12-season system — inclusive across Fitzpatrick I–VI. First analysis free.

You likely have a neutral undertone — a balanced mix of warm and cool. Neutral undertones can wear both metals, though most people have a slight lean (neutral-warm or neutral-cool) that a full color analysis will reveal.
Rose gold is a mix of warm (yellow gold) and cool (pink), so it flatters both neutral and soft warm undertones best. It can also work on cool-neutral skin that leans pink. If you love rose gold but feel unsure about yellow gold, you may be neutral or soft warm.
Use the purest metals you have — sterling silver and 14k+ yellow gold are ideal. Silver-plated brass can have a yellowish tint and gold-filled pieces vary; inconsistent metals give inconsistent results. Aim for bright white silver and true yellow gold.
Yes, platinum reads as a cool metal just like silver. If platinum looks cleaner and brighter on your skin than yellow gold does, that confirms a cool or cool-neutral undertone.
Olive undertones typically find that bright silver looks harsh while yellow gold can look too heavy. Muted or antique gold — a slightly duller, more greenish-gold tone — often looks the most harmonious. Olive is the one undertone where neither extreme metal is the clear winner.
