Calico Archive
Five stops tuned to sit together without fighting — #004b7f ink anchors the set, #72bbff opens it up, and #0073bf, #318fdd, #559fe2 cross the middle in a monochromatic arrangement. Calico Archive suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
