Seafoam Courtyard
Five stops tuned to sit together without fighting — #3f2d89 ink anchors the set, #a6a1f4 opens it up, and #6358b3, #7c73d1, #8b85d6 cross the middle in a complementary arrangement. Seafoam Courtyard suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
