White on neutral-cool, muted skin tones (Soft Summer)

The answer

Yes. White sits inside the Soft Summer palette. The nearest thing in the palette is #D4D0C8, ΔE 10.0 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 white scores across all twelve seasons

White is an opinionated colour: True Winter scores it 98 and Deep Autumn scores it 0. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Soft Summer sits 8 of twelve at 75, 22 points behind True Winter. That gap is the honest size of the compromise, not a verdict on the colour.

• True Winter: 98 (ΔE 1.0).
• Bright Winter: 98 (ΔE 1.0).
• Deep Winter: 95 (ΔE 2.0).
• Soft Summer: 75 (ΔE 10.0) <- this season.
• Deep Autumn: 0 (ΔE 36.7).
