Your colour season is not a matter of taste, intuition, or what an app decides from a selfie. It is determined by three measurable dimensions of your natural colouring — your contrast level, your undertone, and your chroma — and it is confirmed, not guessed, by testing colours against your face. That process has five steps. Four of them you can attempt at home. The fifth is where most self-analyses quietly fall apart.
Step one: capture your colouring honestly
Finding your season is evidence work, and the evidence is your colouring — which means the first task is to see it accurately. Mirrors are unreliable: every room adds a colour cast, and your brain corrects for it without telling you. Photographs, taken properly, do not.
Take four close-up photographs in natural daylight — facing a window or outside under a clear sky, never in direct sun, never at golden hour, never under household bulbs. One of your full face, one in profile, one of your eye region, one of the top of your head. No makeup, none at all — not tinted balm, not a dab of concealer. No self-tanner, and as little natural tan as you can manage. No jewellery, no glasses, no filters.
If your hair is colour-treated, even subtly, it cannot serve as evidence; find photographs of your natural colour, because any lightening warms the hair and will mislead you. Grey hair is a different problem: it does not point you in the wrong direction, but it is evidence with most of the information redacted, so dig out pictures of your pre-grey shade too.
Steps two to four: the three axes
With honest evidence in hand, you work through the three dimensions in turn.
Contrast first. Compare the value — the lightness or depth — of your skin against your hair and eyes. Is the difference very high, high, medium, or low? Your aim is not certainty; it is exclusion. Rule out at least two of the four categories.
Undertone next. Does your skin lean cool, cool-neutral, warm-neutral, or warm? Your skin tone is the primary evidence and your natural hair colour the supporting witness. Your eye colour, despite what most online guides claim, tells you very little about your undertone. Narrowing to two of the four categories is enough.
Chroma last, and hardest. How much grey does your colouring carry? Soft colouring is muted and blended; clear colouring is luminous and saturated, with markers like natural flushing, rosy lips, or vivid eyes. Most people cannot place their own chroma confidently, and that is normal — treat it as an estimate, not a verdict.
Step five: the drape decides
Here is the part that surprises people: even done perfectly, the first four steps will not give you your season. They will give you a shortlist — typically three to six contenders. Analysis can narrow; only draping can confirm.
Draping means holding fabric of a known colour at your collarbone, in neutral daylight, and watching what it does to your face. The wrong colour casts shadows, flattens the skin, makes you look tired in a way that is hard to name. The right one returns structure and light. The difference is real and visible — but seeing it takes practice, a disciplined eye, and fabrics whose colours you actually know. A burgundy jumper from your wardrobe is not a calibrated drape.
What self-analysis can and cannot do
The five steps are worth doing. You will learn to read your own colouring, you will rule out most of the twelve seasons, and you will understand your result far better when you have one. What the home method cannot reliably do is settle a close call — and most people, by step five, are sitting on precisely that. Distinguishing a Soft Summer from a Light Summer, or a Deep Autumn from a Deep Winter, comes down to chroma judgements measured in small degrees, made while looking at your own face, which is the one face you cannot see neutrally.
That is the honest boundary. Get as far as the evidence takes you. When you are down to two seasons and cannot choose, that is not failure — that is the point at which the method asks for a second pair of trained eyes, a full set of drapes, and north-facing light.
