Stormy Delta
Five stops tuned to sit together without fighting — #78230b ink anchors the set, #e89a85 opens it up, and #a34f39, #c16a53, #c97e6a cross the middle in a complementary arrangement. Stormy Delta suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
