Industrial palette
Oat Harbor
Five industrial stops with room to breathe — #7a0017 grounds, #a8393d and #c75556 do the talking, #ce6d6b softens, #ed8886 lifts. The triadic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
