Frost palette
Spruce Dune
Five frost stops with room to breathe — #00495c grounds, #007390 and #318eac do the talking, #539cb6 softens, #70b8d3 lifts. The tetradic bones keep it coherent across tea packaging where the flavor color does the talking. The darkest and lightest stops clear AA as a text pair.
