Petrichor palette
Sumac Parlor
Five stops tuned to sit together without fighting — #006369 ink anchors the set, #7ed7de opens it up, and #009099, #38acb5, #60b9c1 cross the middle in a tetradic arrangement. Sumac Parlor suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
