Petrichor palette
Teal Harbor
Five stops tuned to sit together without fighting — #007380 ink anchors the set, #87e9f9 opens it up, and #00a1b3, #3cbed0, #68cbdb cross the middle in a analogous arrangement. Teal Harbor suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
