Petrichor palette
Saffron Granary
A quiet five-stop petrichor arc with a confident middle — #004952 carries the weight and #70b9c4 carries the air, with #007481, #318f9c and #539da8 bridging in tetradic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
