Blue Hour palette
Mimosa Courtyard
Five stops tuned to sit together without fighting — #9f0003 ink anchors the set, #ffa79a opens it up, and #d14135, #f15f50, #f77b6b cross the middle in a split-complementary arrangement. Mimosa Courtyard suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
