Cobalt blue on warm skin tones with high contrast (Bright Spring)

The answer

Close, but not a match. Cobalt blue sits just outside the Bright Spring palette. The nearest thing in the palette is #3D6BE8, ΔE 14.3 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 cobalt blue scores across all twelve seasons

Cobalt blue is an opinionated colour: True Winter scores it 92 and Light Spring scores it 0. A gap that wide means the colour genuinely decides something, and getting it right is worth the effort.

Bright Spring sits 5 of twelve at 64, 28 points behind True Winter. That gap is the honest size of the compromise, not a verdict on the colour.

• True Winter: 92 (ΔE 3.2).
• Bright Winter: 79 (ΔE 8.5).
• Deep Winter: 74 (ΔE 10.3).
• Bright Spring: 64 (ΔE 14.3) <- this season.
• Light Spring: 0 (ΔE 43.8).
