Sky blue on cool, clear skin tones (True Winter)

The answer

Yes. Sky blue sits inside the True Winter palette. The nearest thing in the palette is #B8C8E0, ΔE 9.3 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 sky blue scores across all twelve seasons

Sky blue is an opinionated colour: Light Summer scores it 87 and Deep Autumn scores it 0. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

True Winter sits 4 of twelve at 77, 11 points behind Light Summer. That gap is the honest size of the compromise, not a verdict on the colour.

• Light Summer: 87 (ΔE 5.0).
• Light Spring: 84 (ΔE 6.5).
• True Summer: 81 (ΔE 7.6).
• True Winter: 77 (ΔE 9.3) <- this season.
• Deep Autumn: 0 (ΔE 35.5).
