Luminous Reef
Five stops tuned to sit together without fighting — #00678f ink anchors the set, #97d9ff opens it up, and #0093ca, #39afe8, #63beef cross the middle in a triadic arrangement. Luminous Reef suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
