Petrichor palette
Leaden Chapel
A quiet five-stop petrichor arc with a confident middle — #00606a carries the weight and #7cd4e0 carries the air, with #008d9b, #37a9b7 and #5fb7c2 bridging in triadic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
