Olive green on cool, clear skin tones (True Winter)

The answer

Close, but not a match. Olive green sits just outside the True Winter palette. The nearest thing in the palette is #007A5E, ΔE 20.8 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 olive green scores across all twelve seasons

Olive green is an opinionated colour: True Autumn scores it 87 and Light Summer scores it 12. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

True Winter sits 7 of twelve at 48, 38 points behind True Autumn. That gap is the honest size of the compromise, not a verdict on the colour.

• True Autumn: 87 (ΔE 5.4).
• Deep Autumn: 80 (ΔE 8.1).
• Soft Autumn: 68 (ΔE 12.7).
• True Winter: 48 (ΔE 20.8) <- this season.
• Light Summer: 12 (ΔE 27.8).
