Glassy Hollow
Five stops tuned to sit together without fighting — #006e92 ink anchors the set, #a0e0ff opens it up, and #009bcb, #3bb8e9, #67c6f0 cross the middle in a tetradic arrangement. Glassy Hollow suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
