Earthy palette
Opal Crater
Five earthy stops with room to breathe — #484200 grounds, #726900 and #8c842b do the talking, #9a934d softens, #b5af68 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.
