Autumn palette
Marble Archive
Five stops tuned to sit together without fighting — #b6280c ink anchors the set, #ffc7bb opens it up, and #e45d44, #ff7e65, #ff9b86 cross the middle in a tetradic arrangement. Marble Archive suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
