Rosy Oasis
Five stops tuned to sit together without fighting — #00516b ink anchors the set, #74c1e4 opens it up, and #007ba1, #3397be, #58a5c6 cross the middle in a split-complementary arrangement. Rosy Oasis suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
