Earthy palette
Golden Oasis
Five earthy stops with room to breathe — #5f6e00 grounds, #869a1b and #a1b641 do the talking, #b2c567 softens, #cee383 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 for large text.
