Rosewood Delta
Five stops tuned to sit together without fighting — #9c2154 ink anchors the set, #ffaec5 opens it up, and #c9537c, #e86f97, #f087a7 cross the middle in a tetradic arrangement. Rosewood Delta suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
