How we measure a runway
From photograph to palette: what our numbers mean, and what they don't.
By the Fashion Field Notes desk · 15 October 2026 · 5 min read
Every look we collect is a photograph from an official runway source. We first separate the clothes from the model, the set and the audience, so that skin, hair and backdrop don't count as colour.
We then measure the colours of the garments themselves and group each pixel into one of thirty-one colour families, from black and charcoal to butter yellow and cobalt blue. A colour 'features' in a look when it covers at least 15% of the clothes.
From the same pixels we measure how light or dark, how vivid or muted, and how textured or smooth the clothes are. These are relative measures: they are most useful for comparing cities, houses and weeks with each other.
Names for fabrics, details and silhouettes come from an AI model that describes each look against a fixed vocabulary. Those appear on the site only once enough looks have been described; until then, sections say so rather than guess.
Numbers describe the runway. They don't replace looking at it.
