Cypress Reef
Five stops tuned to sit together without fighting — #990003 ink anchors the set, #ffa193 opens it up, and #cf392e, #ef584a, #f57565 cross the middle in a analogous arrangement. Cypress Reef suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA as a text pair.
