Canyon palette
Seafoam Archive
Five stops tuned to sit together without fighting — #4f5a00 ink anchors the set, #bbcc73 opens it up, and #758500, #8fa131, #9faf57 cross the middle in a split-complementary arrangement. Seafoam Archive suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
