Harvest Cove
Five stops tuned to sit together without fighting — #a3002b ink anchors the set, #ffabac opens it up, and #d54151, #f55f6b, #fb7b81 cross the middle in a triadic arrangement. Harvest Cove suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
