Lavender on warm, rich skin tones (True Autumn)

The answer

No. Lavender sits well outside the True Autumn palette. The nearest thing in the palette is #C4B394, ΔE 32.2 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.

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 True 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.

True Autumn sits 11 of twelve at 1, 86 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).
• True Autumn: 1 (ΔE 32.2) <- this season.
• Deep Autumn: 0 (ΔE 33.0).
