Twilit Depot
Five stops tuned to sit together without fighting — #004f71 ink anchors the set, #73c0ec opens it up, and #0079aa, #3295c7, #57a3cf cross the middle in a complementary arrangement. Twilit Depot suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
