Acid palette
Sienna Gallery
Five acid stops with room to breathe — #004b5d grounds, #007690 and #3191ac do the talking, #559fb6 softens, #71bbd3 lifts. The tetradic bones keep it coherent across coffee bags and cafe menus that need appetite on crowded shelves. The darkest and lightest stops clear AA as a text pair.
