Sky blue on neutral-cool, muted skin tones (Soft Summer)

The answer

Close, but not a match. Sky blue sits just outside the Soft Summer palette. The nearest thing in the palette is #8B9A9E, ΔE 15.4 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.

Soft Summer sits 8 of twelve at 62, 26 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).
• Soft Summer: 62 (ΔE 15.4) <- this season.
• Deep Autumn: 0 (ΔE 35.5).
