Teal on deep, cool skin tones (Deep Winter)

The answer

Close, but not a match. Teal sits just outside the Deep Winter palette. The nearest thing in the palette is #1E4A3E, ΔE 17.1 away. 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.

Deep Winter sits 6 of twelve at 57, 26 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).
• Deep Winter: 57 (ΔE 17.1) <- this season.
• Bright Winter: 25 (ΔE 30.0).
