Stone Bookshop
Five stops tuned to sit together without fighting — #a01508 ink anchors the set, #ffac9e opens it up, and #cd4e3d, #ed6b58, #f38472 cross the middle in a triadic arrangement. Stone Bookshop suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
