- Hue
- Within 1° of Teal on the hue circle, so the two read as the same colour family at different depths rather than as two colours.
- Lightness
- moderately deeper than Teal — a gap of about 17 lightness steps, which is enough to read as separate up close, though it will compress under a flash.
- Saturation
- Chroma 12, a muted colour. Over a modest area it registers as a colour without becoming the subject, which is what a balanced outfit wants.
- Temperature
- Both cool in undertone, so they agree with the same metals, the same woods and the same light. Shared temperature is what makes two unrelated colours look like they belong together.
- Formality
- Sits comfortably at smart 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 graduation.
- In photographs
- This occasion is mostly photographs, so the camera's behaviour is the decision. Photographs predictably — nothing here is likely to surprise you in the pictures.
- How it goes wrong
- Matching it exactly to the shoes. It reads as a set bought together rather than an outfit assembled deliberately. The strategy-level risk is echoing too closely, which turns a relationship into a failed match.
