Blue Hour palette
Chambray Bazaar
Five stops tuned to sit together without fighting — #00607d ink anchors the set, #7dd3f8 opens it up, and #008cb4, #37a8d1, #60b6da cross the middle in a complementary arrangement. Chambray Bazaar suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
