Blue Hour palette
Simmered Chapel
Five stops tuned to sit together without fighting — #004864 ink anchors the set, #6fb7dd opens it up, and #00719b, #308cb8, #539bc0 cross the middle in a split-complementary arrangement. Simmered Chapel suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
