Deep Winter or True Winter – the difference, precisely.

You have arrived here because you are almost certain you are a Winter. Cool tones flatter you. Warm earth tones drain you. Jewel colours feel like yours. You wear black well, perhaps better than most. But between Deep Winter and True Winter, you cannot quite settle – and the more you read, the less certain you become.

This is the right kind of confusion. The two seasons share more than they differ, and the difference is precise rather than obvious. Let the maison explain.

What they share

Deep Winter and True Winter are both cool. Both belong to the Winter family, which means both reject warmth in clothing – the golden, the rust, the camel, the marigold all sit wrong on you. Both carry the Winter signature of clarity over softness. Neither suits the muted, the dusty, the impressionistic.

Both can wear black with no apology. Both look luminous in true white. Both can carry jewel tones – emerald, sapphire, ruby – with the kind of authority that other seasons cannot quite manage.

If you have ruled out all warm seasons (Spring and Autumn), and ruled out the muted softness of the Summer family, you are correct to be looking here.

What separates them

The distinction lies in a single axis: value.

True Winter is governed by hue. Her defining quality is coolness – pure, blue-based, with no warmth permitted anywhere in her colouring. Her palette is built around the iciest possible whites, the most stark blacks, and the clearest possible jewel tones in between. The relationship between colours within her palette is one of clarity. Nothing is dusty. Nothing is shaded. Each colour feels as if it has been wiped clean.

Deep Winter is governed by value. Her defining quality is depth – the colours run dark, rich, and concentrated. The coolness is present, but it is not the loudest signal. Her palette accepts a small amount of warmth that True Winter cannot – burgundy reads slightly warmer than ruby, deep forest reads slightly warmer than emerald – and the overall sense is one of depth and richness rather than icy clarity.

Put another way: True Winter is winter at dawn, with new snow under a clear sky. Deep Winter is winter at midnight, in a candlelit room lined with deep velvet.

The hair, the eye, the read

Patterns in colouring help orient the reading, though they are not definitive.

True Winter most often has hair of medium-to-dark brown or black, with the cool quality clearly visible – no warm reflections, no golden cast in light. Eyes tend to be deep cool brown, blue, or grey. Skin can be very fair with a cool undertone, deeply pigmented with a cool cast, or anywhere between, but the cool quality is unambiguous.

Deep Winter often shares the dark hair, but the eye is more typically a deep brown, sometimes appearing nearly black. The skin can carry a slight warmth that True Winter cannot – a touch of olive, perhaps, or a depth that reads less icy than True Winter's. Deep Winter is sometimes described as the bridge between True Winter and Deep Autumn – and that description, while imprecise, captures something real.

The sister season

Each of the twelve seasons has a sister – an adjacent classification from which one may borrow with some success. The sister tells you where the season's edges soften.

For True Winter, the sister is True Summer. Both are cool. Where True Winter is clear, True Summer is muted. A True Winter who borrows from her sister will find that some dusty cool blues, soft cool pinks, and grey-mauves can be worn – though never with the same authority as her own clear palette.

For Deep Winter, the sister is Deep Autumn. Both are deep. Where Deep Winter is cool, Deep Autumn is warm. A Deep Winter who borrows from her sister will find that some warm-deep tones – a deep mahogany, a rich forest, a burnt aubergine – can be worn, though always at the warm edge of her comfort rather than at her cool centre.

This is the cleanest diagnostic test the maison knows. If True Summer feels like a place you could live in, you are likely True Winter. If Deep Autumn feels survivable, you are likely Deep Winter.

The colour test

Hold three colours to your face, in natural light, without makeup.

Test one – pure black. Both seasons wear it. Note whether your face brightens or fades.

Test two – icy pink (a clear, cold pink with no dust). A True Winter is lifted by it. A Deep Winter is not diminished by it, but does not light up the way the True Winter does.

Test three – burgundy (a deep wine red with slight warmth). A Deep Winter is anchored by it. A True Winter is not destroyed by it, but feels more at home in a clearer cherry red.

The colour that lifts your face the most tells the reading. Not the colour you find most beautiful in the abstract – the colour that brightens your own complexion when held against it.

Where readers go wrong

Three errors recur often enough to warrant naming.

First, mistaking depth for warmth. Many self-classifiers see darker colours flattering them and assume Autumn. The diagnostic question is not "do dark colours suit me" but "do dark and cool colours suit me." A Deep Winter is not warm – she is deep and cool together.

Second, mistaking clarity for brightness. Bright Winter and True Winter are sometimes confused with one another for this reason. Brightness implies high chroma, not merely clarity. True Winter is clear but not necessarily vivid; Bright Winter is genuinely vivid.

Third, mistaking olive skin for warmth. Olive complexions can read as either Winter or Autumn depending on the underlying undertone. A cool olive can sit cleanly in Deep Winter. A warm olive cannot. The Mauve Lip Test – holding a pure cool mauve against the lips – separates these, and is part of the maison's diagnostic for this reason.

The reading the maison would give

A True Winter reading carries the language of clarity, iciness, jewel-clear cold. The colours are crisp; the contrast is sharp; the palette photographs almost like stained glass against a cold ground.

A Deep Winter reading carries the language of depth, richness, low light. The colours are saturated; the contrast can be present but is more often internal – within the palette itself rather than between the wearer and her clothes. The palette photographs like an old library at evening, with jewel-tones glowing from the dark.

Both are striking. Neither is more beautiful than the other. The reading is correct when the wearer recognises herself in the language used, and when her best colours – the ones she has always known suited her – appear in the palette returned.

If you have read this far and remain uncertain, the maison would offer one closing observation. The most reliable test is not analytical but experiential. Wear a Deep Winter palette for a week, and a True Winter palette for the week after. Notice which week you receive more compliments. Notice which week you feel most like yourself. The body knows what the mind cannot quite settle.
