Lavender on deep, cool skin tones (Deep Winter)

The answer

No. Lavender sits well outside the Deep Winter palette. The nearest thing in the palette is #F2F2F0, ΔE 26.2 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 lavender scores across all twelve seasons

Lavender is an opinionated colour: Light Spring scores it 87 and Deep Autumn scores it 0. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Deep Winter sits 9 of twelve at 34, 53 points behind Light Spring. That gap is the honest size of the compromise, not a verdict on the colour.

• Light Spring: 87 (ΔE 5.2).
• True Summer: 80 (ΔE 7.8).
• Light Summer: 78 (ΔE 8.8).
• Deep Winter: 34 (ΔE 26.2) <- this season.
• Deep Autumn: 0 (ΔE 33.0).
