Teal on cool, light skin tones (Light Summer)

The answer

No. Teal sits well outside the Light Summer palette. The nearest thing in the palette is #8E9299, ΔE 24.5 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 teal scores across all twelve seasons

Teal is an opinionated colour: True Autumn scores it 83 and Bright Winter scores it 25. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Light Summer sits 10 of twelve at 39, 44 points behind True Autumn. That gap is the honest size of the compromise, not a verdict on the colour.

• True Autumn: 83 (ΔE 6.9).
• True Winter: 82 (ΔE 7.4).
• True Summer: 72 (ΔE 11.3).
• Light Summer: 39 (ΔE 24.5) <- this season.
• Bright Winter: 25 (ΔE 30.0).
