Tranquil Kiosk
Five stops tuned to sit together without fighting — #007669 ink anchors the set, #91eadb opens it up, and #2ca393, #50c0af, #74cdbe cross the middle in a tetradic arrangement. Tranquil Kiosk suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
