Blue Hour palette
Raisin Bluff
Five stops tuned to sit together without fighting — #6b2900 ink anchors the set, #e39570 opens it up, and #9f4a1c, #bd6539, #c57955 cross the middle in a split-complementary arrangement. Raisin Bluff suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
