Midcentury palette
Perennial Brook
Five stops tuned to sit together without fighting — #00726f ink anchors the set, #87e7e3 opens it up, and #0ea09c, #40bdb8, #69cac5 cross the middle in a tetradic arrangement. Perennial Brook suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
