Most frame-color guides are built around clearly warm or clearly cool undertones, which leaves neutral and olive skin without much specific guidance beyond "you can wear anything" — true in a broad sense, but not the most useful advice if you're actually trying to choose a frame.
Neutral undertone: genuinely the most flexible
A neutral undertone is a balanced mix of warm and cool — the wrist-vein test that usually distinguishes warm (greenish veins) from cool (bluish veins) often comes back ambiguous or mixed for a true neutral. That balance means the warm/cool axis simply isn't the limiting factor when choosing a frame color the way it is for strongly warm or cool skin.
That flexibility is worth using deliberately rather than defaulting to black or the most popular tortoise on the wall. Colors that would look slightly off against strongly warm or strongly cool skin — a true grey, a muted rose-gold, an ambiguous warm-cool tortoise — tend to sit comfortably on a neutral undertone.
Olive undertone: flexible, but not identical to neutral
Olive skin has a distinct green or golden-green cast, which technically places it in the neutral-to-warm range but gives it its own specific behavior with certain colors. Olive skin generally handles both warm and cool frame colors better than a strongly warm or strongly cool undertone would — but it has a specific blind spot: colors that carry their own green or yellow-green cast.
What works well on olive skin: warm browns and tortoise, gold-toned metal, burgundy and deep red acetate, and black, which reads cleanly against most olive tones without competing.
What to be more careful with: khaki or army-green tones, and yellow-gold finishes with a strong yellow (rather than warm-gold) cast. These echo the same undertone already present in olive skin rather than contrasting with it, which can make both the frame and the skin look slightly duller than either would look separately.
Why "you can wear anything" isn't quite the full story
It's true that neutral and olive undertones have more room to work with than strongly warm or cool skin, but "anything works" undersells the point. The real advantage is being able to choose based on what you actually like — a color, a finish, a mood — rather than being constrained to a narrow warm or cool palette the way other undertones are. That's a genuine advantage worth using, not a reason to stop thinking about color at all.
The bottom line
Neutral undertones have the broadest frame-color flexibility of any skin tone; olive undertones are nearly as flexible but should watch for colors with their own green or yellow-green cast. Use the flexibility to try frame colors you might not otherwise consider, rather than defaulting to the safest option in the case.

Frequently Asked Questions
What's the difference between neutral and olive undertones?
Neutral undertone means an even balance of warm and cool, without a strong lean either direction. Olive undertone is more specific — a distinct green or golden-green cast to the skin, which is technically still in the neutral-to-warm range but behaves differently with certain colors than a true neutral does.
What frame colors work well for olive skin specifically?
Warm browns, tortoise, gold metal, and burgundy or deep red tones tend to work well against olive skin — they contrast with the green undertone rather than competing with it. Black also works cleanly on most olive skin tones.
What frame colors should olive skin avoid?
Frame colors with their own yellow-green or olive-adjacent cast — certain khaki or army-green tones, some yellow-gold finishes — can clash with olive undertones rather than complementing them, since they echo the same undertone instead of contrasting with it.
Can neutral undertones really wear any frame color?
Close to it, more than any other undertone category — but "neutral" doesn't mean "no undertone," it means a balanced mix of warm and cool. Very saturated or unusual colors can still clash regardless of undertone; neutral just means the warm/cool axis specifically isn't the limiting factor.
