Umber Manor
Five stops tuned to sit together without fighting — #890001 ink anchors the set, #ff8e7e opens it up, and #c13025, #e15041, #e76c5d cross the middle in a triadic arrangement. Umber Manor suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA as a text pair.
