Frost palette
Mustard Library
A quiet five-stop frost arc with a confident middle — #005f6b carries the weight and #7cd2e0 carries the air, with #008b9c, #37a7b8 and #5eb5c3 bridging in monochromatic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
