Mauve on cool, soft skin tones (True Summer)

The answer

Yes. Mauve sits inside the True Summer palette. The nearest thing in the palette is #9E7C98, ΔE 3.9 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.

True Summer is the top of that list. No season wears mauve better, which is worth knowing before you talk yourself out of it.

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