Petrichor palette
Sienna Library
A quiet five-stop petrichor arc with a confident middle — #7b3800 carries the weight and #fba36f carries the air, with #b65600, #d4722e and #dc8753 bridging in tetradic formation. Built for hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
