Coral Reef
Five stops tuned to sit together without fighting — #00689a ink anchors the set, #a5d9ff opens it up, and #2993d0, #4cafee, #6fbff4 cross the middle in a monochromatic arrangement. Coral Reef suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
