Restful Depot
Five sumi stops with room to breathe — #9b1800 grounds, #d1432b and #f16148 do the talking, #f77c65 softens, #ffa896 lifts. The split-complementary bones keep it coherent across packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
