Frost palette
Birch Delta
Five stops tuned to sit together without fighting — #005050 ink anchors the set, #73c1c0 opens it up, and #007c7c, #339797, #57a5a4 cross the middle in a analogous arrangement. Birch Delta suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
