Autumn palette
Thistled Brook
Five stops tuned to sit together without fighting — #720f56 ink anchors the set, #e28ec1 opens it up, and #9d417d, #bb5c98, #c472a4 cross the middle in a tetradic arrangement. Thistled Brook suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
