Mauve on deep, warm skin tones (Deep Autumn)

The answer

Close, but not a match. Mauve sits just outside the Deep Autumn palette. The nearest thing in the palette is #8A7660, ΔE 20.2 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 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.

Deep Autumn sits 7 of twelve at 50, 41 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).
• Deep Autumn: 50 (ΔE 20.2) <- this season.
• Deep Winter: 28 (ΔE 28.7).
