Opal Oasis
Five stops tuned to sit together without fighting — #005684 ink anchors the set, #87c6f7 opens it up, and #307fb4, #4e9bd1, #6baad9 cross the middle in a complementary arrangement. Opal Oasis suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
