Marble Cove
Five stops tuned to sit together without fighting — #00646a ink anchors the set, #7ed8df opens it up, and #00919a, #38adb6, #61bbc2 cross the middle in a complementary arrangement. Marble Cove suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
