Rust on cool, light skin tones (Light Summer)

The answer

No. Rust sits well outside the Light Summer palette. The nearest thing in the palette is #8E9299, ΔE 34.4 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. Rust lands within ΔE 9.9 of #8B4513, which is on the short list of colours that actively work against Light Summer colouring. That is the failure people can see and cannot name.

How rust scores across all twelve seasons

Rust is an opinionated colour: True Autumn scores it 88 and Light Summer scores it 0. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Light Summer sits 12 of twelve at 0, 88 points behind True Autumn. That gap is the honest size of the compromise, not a verdict on the colour.

• True Autumn: 88 (ΔE 5.0).
• Deep Autumn: 87 (ΔE 5.1).
• True Spring: 71 (ΔE 11.8).
• Light Summer: 0 (ΔE 34.4) <- this season.
