Tranquil Crater
Five blue hour stops with room to breathe — #005d7a grounds, #0088b1 and #36a4ce do the talking, #5eb2d6 softens, #7bcff4 lifts. The analogous bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
