Petrichor palette
Ebony Cottage
A quiet five-stop petrichor arc with a confident middle — #004f53 carries the weight and #73c0c4 carries the air, with #007b80, #33969b and #56a4a7 bridging in tetradic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
