Prairie palette
Granite Fjord
Five prairie stops with room to breathe — #006668 grounds, #009396 and #39afb2 do the talking, #61bcbe softens, #7fdadc lifts. The triadic 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.
