Petrichor palette
Fennel Mill
Five stops tuned to sit together without fighting — #006873 ink anchors the set, #81dce9 opens it up, and #0095a4, #39b1c0, #63bfcc cross the middle in a tetradic arrangement. Fennel Mill suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
