Mauve on neutral-warm, muted skin tones (Soft Autumn)

The answer

Close, but not a match. Mauve sits just outside the Soft Autumn palette. The nearest thing in the palette is #A87868, ΔE 14.6 away. 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 mauve scores across all twelve seasons

Mauve is an opinionated colour: True Summer scores it 90 and Deep Winter scores it 28. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Soft Autumn sits 3 of twelve at 64, 27 points behind True Summer. That gap is the honest size of the compromise, not a verdict on the colour.

• True Summer: 90 (ΔE 3.9).
• Soft Summer: 87 (ΔE 5.3).
• Soft Autumn: 64 (ΔE 14.6) <- this season.
• Deep Winter: 28 (ΔE 28.7).
