Grey on warm, light skin tones (Light Spring)

The answer

Close, but not a match. Grey sits just outside the Light Spring palette. The nearest thing in the palette is #A8917A, ΔE 12.5 away, which is one of the four neutrals the season is built on. Under 12 reads as the same colour family; past 25 the two are visibly different colours.

It does not collide with anything on the season's avoid list, so the only question is distance.

How grey scores across all twelve seasons

Grey is an opinionated colour: Light Summer scores it 88 and True Spring scores it 32. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Light Spring sits 6 of twelve at 69, 19 points behind Light Summer. That gap is the honest size of the compromise, not a verdict on the colour.

• Light Summer: 88 (ΔE 4.7).
• Soft Summer: 87 (ΔE 5.3).
• True Winter: 86 (ΔE 5.8).
• Light Spring: 69 (ΔE 12.5) <- this season.
• True Spring: 32 (ΔE 19.9).
