Topaz Oasis
Five stops tuned to sit together without fighting — #005e7d ink anchors the set, #7bd0f8 opens it up, and #0089b5, #37a5d2, #5eb3da cross the middle in a complementary arrangement. Topaz Oasis suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
