Golden Bluff
Five stops tuned to sit together without fighting — #005f75 ink anchors the set, #7cd2ee opens it up, and #008baa, #37a7c7, #5fb5d0 cross the middle in a tetradic arrangement. Golden Bluff suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
