Petrichor palette
Harbor Manor
Five stops tuned to sit together without fighting — #004f56 ink anchors the set, #73bfc9 opens it up, and #007a85, #3295a0, #56a3ac cross the middle in a split-complementary arrangement. Harbor Manor suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
