Opera palette
Cypress Glade
Five opera stops with room to breathe — #00455f grounds, #006e96 and #2f89b2 do the talking, #5197bb softens, #6eb4d8 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.
