Blue Hour palette
Woolen Pagoda
Five stops tuned to sit together without fighting — #a72300 ink anchors the set, #ffb8a8 opens it up, and #d5573c, #f57457, #fb8c73 cross the middle in a split-complementary arrangement. Woolen Pagoda suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
