Amber Ridge
Five stops tuned to sit together without fighting — #8f3c00 ink anchors the set, #ffb48e opens it up, and #cb5b0a, #ea7735, #f18e5a cross the middle in a tetradic arrangement. Amber Ridge suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
