Blue Hour palette
Evening Harbor
Five stops tuned to sit together without fighting — #a53500 ink anchors the set, #ffbfaa opens it up, and #d66036, #f67c53, #fc9471 cross the middle in a tetradic arrangement. Evening Harbor suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
