Acid palette
Powdery Fjord
Five acid stops with room to breathe — #004c47 grounds, #007870 and #32938b do the talking, #54a098 softens, #71bdb4 lifts. The complementary bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
