Retro palette
Twilit Prairie
Five retro stops with room to breathe — #6e2e00 grounds, #a84b00 and #c6662b do the talking, #ce7b4d softens, #ed9769 lifts. The monochromatic 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.
