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

The answer

No. Lavender sits well outside the Soft Autumn palette. The nearest thing in the palette is #C4A890, ΔE 27.6 away. Under 12 reads as the same colour family; past 25 the two are visibly different colours.

There is a second problem. Lavender lands within ΔE 8.8 of #C4C0E0, which is on the short list of colours that actively work against Soft Autumn colouring. That is the failure people can see and cannot name.

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.

Soft Autumn sits 10 of twelve at 13, 74 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).
• Soft Autumn: 13 (ΔE 27.6) <- this season.
• Deep Autumn: 0 (ΔE 33.0).
