Emerald green on deep, cool skin tones (Deep Winter)

The answer

Close, but not a match. Emerald green sits just outside the Deep Winter palette. The nearest thing in the palette is #1E4A3E, ΔE 21.9 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 emerald green scores across all twelve seasons

Emerald green is an opinionated colour: True Winter scores it 84 and Light Summer scores it 31. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Deep Winter sits 9 of twelve at 45, 39 points behind True Winter. That gap is the honest size of the compromise, not a verdict on the colour.

• True Winter: 84 (ΔE 6.3).
• True Autumn: 71 (ΔE 11.6).
• True Summer: 64 (ΔE 14.4).
• Deep Winter: 45 (ΔE 21.9) <- this season.
• Light Summer: 31 (ΔE 27.5).
