Daylight palette
Sienna Reef
Five daylight stops with room to breathe — #004a4c grounds, #007579 and #319094 do the talking, #539da0 softens, #70babd lifts. The tetradic bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
