Thistled Ridge
Five stops tuned to sit together without fighting — #892144 ink anchors the set, #fb9db2 opens it up, and #b5506b, #d46b85, #dc8196 cross the middle in a tetradic arrangement. Thistled Ridge suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
