- Hue
- Roughly opposite Charcoal on the hue circle, which is maximum separation and reads unmistakably as a deliberate contrast.
- Lightness
- Almost the same lightness as Charcoal. Two areas at the same depth merge at a distance and in photographs, so this only works when the two are separated by texture or by a third element between them.
- Saturation
- Chroma 10 — effectively a neutral. Across a modest area that is the point: it holds the outfit together without asking for attention.
- Temperature
- Warm against a cool charcoal — a deliberate temperature contrast. It works, but it commits: the metals and the shoes then have to pick a side.
- Formality
- Sits comfortably at casual, neither dressing the outfit up nor down.
- Fabric
- Whatever fabric this ends up in will shift the colour: a pile or a nap reads deeper, a satin or a silk reads lighter along the highlight. Match sheen before you match shade.
- Season
- Season and climate change what this colour looks like more than most people expect — direct summer sun saturates, flat winter light does the opposite.
- Where you will be
- Expect mixed indoor and daylight at a office and workplace.
- In photographs
- Cameras compress tonal differences, so two areas this close in lightness are likely to merge into one shape in a photograph even though they look distinct in the room.
- How it goes wrong
- Shoes lighter than the trousers, which draws attention downward and shortens the line — occasionally the intention, usually not. The strategy-level risk is landing in the near-miss band — close enough to the anchor to look like an attempted match, far enough to fail it.
