Blue Hour palette
Herbal Bookshop
Five stops tuned to sit together without fighting — #9b1c00 ink anchors the set, #ffaa98 opens it up, and #ca4f37, #ea6c52, #f0846d cross the middle in a tetradic arrangement. Herbal Bookshop suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
