Mercurial Harbor
Five stops tuned to sit together without fighting — #ae3300 ink anchors the set, #ffc6b4 opens it up, and #e55a2d, #ff7d55, #ff997a cross the middle in a tetradic arrangement. Mercurial Harbor suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
