Blue Hour palette
Cornsilk Brook
Five stops tuned to sit together without fighting — #a83123 ink anchors the set, #ffc0b5 opens it up, and #d56150, #f47d6b, #fb9483 cross the middle in a split-complementary arrangement. Cornsilk Brook suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
