Denim Lighthouse
Five stops tuned to sit together without fighting — #a43652 ink anchors the set, #ffc1cb opens it up, and #d1647b, #f08096, #f897a8 cross the middle in a monochromatic arrangement. Denim Lighthouse suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
